A The hind brain is composed of - Cerebellum - Medulla - Pons The thalamus is situated between the cerebral cortex and midbrain. Therefore it is not a part of the hind brain.

The two components of autonomous nervous system have antagonistic actions. But in certain cases their effects are mutually helpful. Which of the following statement is correct?
1 At rest, the control of heart beat is not by the vagus nerve
2 During exercise the sympathetic control decreases
3 During exercise the parasympathetic control decreases
4 Stimulation of sympathetic system results in constriction of the pupil
Explanation:
C During exercise, the parasympathetic control decreases. During exercise, sympathetic control increases to prepare the body for physical activity, and the parasympathetic control decreases. This allows for the "fight - or -flight" response, which leads to increased heart rate, dilation of airways, and more blood flow to the muscles. The sympathetic nervous system dominates during exercise to meet the body's increased demands.

Which are the longest cells in the body of man?
1 Muscle cells of legs
2 Bone cells
3 Nerve cells
4 None of the above
Explanation:
C Nerve cells are the longest cells in the body of a man. These neurons are up to 1-1.5 meter in length and can extend from the spinal cord to the toes, making them some of the longest single cells.
A The hind brain is composed of - Cerebellum - Medulla - Pons The thalamus is situated between the cerebral cortex and midbrain. Therefore it is not a part of the hind brain.
