Salivary Gland -Digestive System

           Salivary Glands

         Salivary glands|  They are the exocrine glands which are ectodermal in origin.
Salivary glands are usually three pairs in Human Beings. The number of Salivary glands in Rabbit is four.
The major function of Salivary gland is to secrete saliva.
The main three salivary glands of Human beings are.

1. Parotid Gland
2. Sub Lingual Glands
3. Sub Mandibular (Sub Maxillary) Glands.  

Each of them are now explained in details.

Parotid Glands

• They are the largest salivary gland in human beings. 
  
• They are situated near our ears. 
• The duct of Parotid Gland is called Stensen's Duct which opens near the second upper molar teeth. 
• These glands secretes Alpha-amylase (ptyalin). which help in digestion of starch (breaks starch into Maltose and Dextrin).

Sub Lingual Glands

• They are the small sized salivary glands 
• They are situated at the ventral portion (base) of tongue. 
• The duct of Sub Lingual gland is called Duct Of Rivinus. 

Sub-Mandibular Gland

• They are also called Sub-maxillary or Wharton's Gland.
  
• They provide the largest contribution to the volume of saliva (70%)
• They are situated at angles of lower jaw. 
• The duct of Sub Mandibular Gland is called Wharton's Duct.

Sub Mandibular and Sub Lingual salivary glands secretes amylase (ptyalin) and mucin.   

 

Salivary Glands Functions

Functions of salivary Glands

1. It helps in lubrication and binding of masticated food into bolus.
2. Saliva contains lysozymesand thiocyanates which kill the bacteria.
3. It provides alkaline buffering.

Saliva 

        It contains 99.5% water, IgA, mucous, mucin, ptyalin, lysozyme, thiocyanates, urea, uric acid, HCO3, Na+, K+ Cl- etc.

Saliva are slightly acidic in Carnivores and alkaline in Ruminants .

Nice to know

• Infra orbital is the Rabbits but they are absent in humans.
• Parotid salivary gland is modified into labial poisonous glands in most snakes.
• Salivary glands are absent in frog, toad, sea cow and whale.

  Neuroglial Cells - Nervous System

 

             
 Neuroglial cells | Neuroglial cells are also known as supporting cells of Nervous System. They alosplay very significant role in the conduction of nerve impulses. Without them its almost impossible for brain and whole Nervous systems to work properly.

              There are many supporting cells in our Nervous system. Some of them are Mentioned below. 

1. Astrocytes
2. Microgliai
3. Satellite cells
4. Schwann cells
5. Oligodendrocytes
6. Ependymal cells

Each of above are explained in details below:

1.Astrocytes

•  They are the star shaped neuroglial cells.
•   They are the most abundant neuroglial cells found in human body th am other neuroglial cells. 
  
• Their main function is to control the chemical composition of all the neurons. 
• They also forms Brain Blood Barrier (BBB)   

 2. Microglia 

•   They are the smaller sized neuroglial cells.
  
•   They acts as the phagocytes of whole nervous system.

3. Satellite cells 

•  They are around all the other Neuroglial cells
• They surround the cell bodies of neurons of Peripheral Nervous System (PNS). 

4. Schwann cells

  They form myelin sheath in the axons of Peripheral Nervous System (PNS).        

5. Oligodendrocytes

• They main function is to form myelin sheath in the axons of Central Nervous System (CNS).                                  

6. Ependymal cells

• They lines the ventricles and central canal.

They contains microvilli and cilia in them.   

Nice to know 

Gyri (singular-gyrus) :- They are the ridges (elevations) in cerebrum.

Sulci (singular-sulcus) :- They are the  Grooves (depressions) in cerebrum.

Fissure :- They are deep sulcus present in brain.

Association tracts :- They are the axons that connect gyri in the same hemisphere.

Commissural tracts :- They are the axons that connect gyri in one hemisphere to the corresponding gyri in the other hemisphere.

 Eg. Corpus callosum, anterior commissure, posterior commissure.

Insula :- It is considered as 5th lobe by sime scientists. It lies beneath the temporal lobe.

      Terms related to Nervous System 

• Nucleus

Narendra Modi - The worst Prime Minister??

        Narendra Modi - The worst Prime.                                        Minister?? 

 
     Narendra Modi presently working as the Prime Minister of India since 2014.
 This is his second period of ruling the country as the Prime Minister. There may be many reasons why he is still being loved by crores of Indian citizens.

He has done uncountable reformations in Indian Land.  He has made raised the name of India in only very few years.  Currently he belongs to the party BJP
           
               Even though he is still not able to solve the problem of poverty, he is still being loved by many people specially Hindu Religious People.
He has created a type of non-secularism in  the country.
       Recently he joined inaugaration ceremony for construction of   Ram Mandir In Ayodhya. 

                   Its not bad construting the Religious places in the country but in the pandemic of Covid19 virus, where many people are dying of hunger,  natural calamity like flood, and many more instead of helping them with pure heart , he is interested in construction of the Temple with a very very large budget. 

                He is the PM of India, he should think the development of all the states equally. But, not you can see Bihar how underdeveloped it is.
 
         Even Rahul Gandhi, the President of Indian National Congress party is not matured to run a huge country like INDIA.
 He even doesn't know to speak infeont of audience . He has no clue how the country and government works. He can't express his own idea without help of gis personal secretary. 

                    Before BJP was on rule,  country wasn't able to make a large progress.  Reformations were rarely able to see. People couldn't live with proper guidance of government. Only the capital nad large cities were kept on focus of development.

               Rahul Gandhi's ancestors were the main reason behind the creation of conflict betwee n Pakistan and India.
He should have done the proper judgement that time but created unwanted diplomatic relationship.
        Please share this post if you are a true Indian.
Please comment down the political party you support and give the reason behind supporting the party.  
   NOTE: This blog is not written for any Hate purpose. We are nit supporting any specific party. We are creating only awareness among people.
   

COVID-19 vaccine Successfully Launched or Its Fake?

      Russia Launches Covid19 Vaccine 
         

                          Russia claims that They have successfully prepared the COVID 19 vaccine.  They have launched this vaccine after their so called 3 trial phases.
                      Russian President claims that he launched this vaccine after trying it on many volunteers and even his one daughter out of two daughters.
      Earlier it was said that the vaccine will be launched on 12th of August, 2020.
 This vaccine will officially be available for trahis country from 14th of August, 2020.
   Currently, Russia's vaccine is not among those vaccines that are listed on WHO's list of six Covid Vaccines.

    Talking about the details of Covid Vaccine prepared by Russia,  They used adapted strains of adenovirus, a virus that causes common cold, to trigger an immune response.
This can be considered as the Victory of Human kind's over Covid 19.
   Russia is fast-tracking its Vaccine at an very extraordinary pace. Russia also says just being first is not enough, you must also be successful. Russian Officials have n as med it Sputnik-V , in the honor of world's first satellite sent to the space.
     

After testing this vaccine upon many corona patients, it has been concluded that their health condition is normal without any side effects and also guaranteed immunity responses for about 2 years with this Corona Virus.
      Its upon them that when they will produce on large scale and Distribute them to world wide and win over Covid Virus soon.  Officials also they that they plan for Mass vaccination from October month 2020.

Share as much as possible if you really want this pandemic to get over.

What Is Cardiac Cycle? Cardiac cycle steps

                       Cardiac Cycle
                Cardiac Cycle | Cardiac cycle refers to the event that occurs from the beginning of one heart beat to beginning of next heart beat.
    It is a continuous process running every time in the heart of each and every living organisms.  
              

• Talking about Healthy human being, the cardiac cycle lasts for 0.8 seconds ( if the heart rate is 72 beats per minute ).
•  The contraction of of Auricles is called auricular systole and the relaxation is called auricular diastol. Similarly, the contraction of ventricles is called ventricular systole and the relaxation is called ventricular diastole.    
•  Joint diastole: Its the period during which entire heart is in diastolic phase. It lasts fpr 0.4 seconds normally.

                           Phases of Cardiac Cycle.
    There are basically 4 different phases of cardiac cycle in human body.
1. Ventricular Systole
2. Ventricular Diastole.  
3. Auricular Systole

4. Auricular Diastole
          So lets learn all these phases in complete details. 
1. Ventricular Systole
          In this phase, The Blood is pumped out of the venticles through arteries. 
          During ventricular Systole ,the auricles receive impure blood from the veins.

     *This process has four main sub-phases.
     a. Isovolumetric contraction Cuspid valves of heart close during this phase and produce "LUBB" sound.
     b. Its the period of ejection of blood 
     c. Also called protodiastole
     d. Volumetric relaxation .   

2. Ventricular diastole.
       Closure of semilunar valves occurs due to which "DUP" sound is heard at the onset of ventricular diastole.
 This phase has two stages:
   ~Rapid inflow :-S3 heart sound is produced during this phase.
   ~Diastasis: In this phase, pressure inside all four chambers is equal and entire heart is in diastole. The AV valves are open but semilunar valves are closed during this phase.

Keywords:blood, cardiac cycle, cardiac cycle define, cardiac cycle definition, cardiac cycle diagram, cardiac cycle events, cardiac cycle phases, cardiac cycle steps, heart, 

 3. Auricular systole :
                   In this phase S4 heart sound is produced . Also the Contraction of Auricles take place this phase.

4. Auricular diastole : The phase is identified by the relaxation of walls of auricles.
       This phase has some important topic that needs to known by all.
      ~ stroke volume - It is the volume of blood pumped from heart (left ventricle ) into the systemic aorta in one heart beat.
      ~ cardiac output - Its the volume of blood pumped from heart ( left ventricle ) into the systemic aorta in one minute.                 

         It is also called minute volume.
           Cardiac output =
      Stroke volume * Heart rate=70 ml * 72 times/minute = 5040 ml/ minute = 5 litres/ minute.
       Total amount of blood in human body is about 5 litres (7% of body weight ).,During mild exercise , the cardiac output rises to about 11 litres l. Cardiac output is directly proportional to the size of the organism, metabolic rate but it is inversely proportional to age.
