Question : Draw a neat and labelled diagram of human brain. Mention its various parts and functions.

Answer»

SOLUTION :The brain is the central information processing organ of our body and acts as the .command and control system..
Functions of brain :
It controls the voluntary movements, balance of the body, functioning of VITAL involuntary organs (e.g., lungs, heart, kidneys), thermoregulation, hunger and thirst, circadian (24-hour) RHYTHMS of our body, activities of several endocrine glands and. human behaviour.
It is also the site for processing of vision, hearing, SPEECH, memory, intelligence, emotions and thoughts.
The human brain is well protected by the SKULL.
Inside the skull, the brain is covered by cranial meninges.
It is formed of 3 layers :
(1) Dura mater - outer layer
 (2) Arachnoid - middle thin layer
(3) Pia mater - inner layer (which is in contact with brain tissue)
The brain can be divided into three major parts:
(a) Forebrain (b) Midbrain (c) Hindbrain

Question : Draw a labelled diagram showing interal structureof heart .

Answer»

Solution :
The entire heart is made of cardiac muscles. The walls of ventricles are much thinker tan that of the atria.
A specialised cardiac musculature called the nodal tissue is also distributed in the heart. A patch of this tissue is present in the right upper cornor if the right ATRIUM called he sino-artical node (SAN).
Another MASS of this tissue is seen in lower left coron of the right atrium close to the atrio ventricular septum called the atrio ventricular node (AVN).
A bundle of nodal fibres atrio through the atrio ventricular septa to emerge on the top of the inter ventricular septum and immediately divides into a right and left bundle.
These branches give rise to minute fibres throughout the ventricular musculature of the respective sides and are called PURKINJE fibres.
These fibres ALONG with right and left bundle are KNOWN as bundle of HIS.
The nodal musculature has the ability to generate action potentials without any external stimuli. ie. it is autoexcitable.
However the number of action potentials that could br generated in a minute vary at different parts of nodal system. The SAN can generate the maximum number of action potentials. ie. - 70 -75 `min^(-1)` and is responsible for intitiating and maintaining the rhythmic contractile activity of the heart. Therefore it is called the pacemaker.
Our heart normally beats 70-75 times in a minute (average 72 beats `min^(-1)`.

Question : Draw a labelled diagram of T. S. of Intestine.

Answer»

Solution :The WALL of alimentary canal from oesophagus to rectum possesses four layers :
(a) Scrosa : Serosa is the outermost layer and is made up of a thin mesothelium.
(b) Muscularis : It is formed by smooth muscles usually arranged into an inner circular and outer longitudinal layer.
(c) Sub-mucosa : The sub-mucosal layer is formed of loose connective tissues containing nerves, blood and lymph vessels. In doudenum, gland are also present in sub-mucosa.
(d) Mucosa : Inner most layer lining the lumen of the alimentary canal is mucosa. This layer forms irregular folds and small finger-like projections called villi in the stomach.

In the intestine, small finger like folding called villi are located.
The cells lining the villi PRODUCE numerous microscopic projections called microvilli.
It appears like brush border. These modifications increase the surface AREA enormously.
Villi are supplied with a network of capillaries and a LARGE lymph vessel called the lacteal are located.
Mucosal epithelium has goblet cells which secrete mucus.
That HELP in lubrication.
Mucosa also forms glands in the stomach and crypts in between the bases of villi in the intestine. (Crypts of Lieberkuhn)
All the four layers show modification in different parts of this alimentary canal.

Question : Draw a labelled diagram of human digestive system.

Answer»

Solution :The organs taking part in ingestion of food, digestion, absorption and egestion are called digestive organs.
For e.g, MOUTH, tongue, teeth, pharynx, alimentary canal, stomach, small INTESTINE, LARGE intestine, RECTUM, anus.
Digestive organs include some subsidiary glands LIKE saliva, liver and pancreas.
The system formed by co-ordination of all these organs is called digestive system.
