(3) Dendrons and non-myelinated axons
(4) All of the above
Answer: 4
Explanation: White matter in the nervous system consists mainly of myelinated axons, which include telodendria, cell bodies, dendrons, and non-myelinated axons.
6. Which role of neurons regarding different kinds of stimuli is absent_______
(1) detect
(2) receive
(3) transmit
(4) protect
Answer: 4
Explanation: Neurons detect, receive, and transmit various stimuli but do not have a role in protecting the body against external stimuli.
7. The direction of against stimulus-response is opposite in which of the following reflex action?
(1) Biceps tendon reflex
(2) Knee jerk reflex
(3) Tricep tendon reflex
(4) Withdrawal reflex
Answer: 4
Explanation: In a withdrawal reflex, the response (movement away from the stimulus) is opposite to the direction of the initial stimulus.
8. At least how many afferent and efferent neurons and involved in any reflex action?
(1) One afferent, one efferent neuron
(2) One afferent, two efferent, one interneuron
(3) One afferent, one efferent, two interneuron
(4) Two efferent, one efferent, one interneuron
Answer: 1
Explanation: A reflex action involves a sensory (afferent) neuron carrying information to the central nervous system and a motor (efferent) neuron carrying the response away from the CNS.
9. The group of cranial nerves that are associated with the movement of eye ball are____________
(1) I, II, VIII
(2) III, IV, VI
(3) VII, IX, XII
(4) III, IV, VII
Answer: 2
Explanation: Cranial nerves III (oculomotor), IV (trochlear), and VI (abducens) are responsible for controlling the movements of the eyeballs.

10. The somatic nervous system is formed by________
(1) Ramus dorsalis
(2) Ramuscommunicationss
(3) Ramus ventralis
(4) Both 1 & 3
Answer: 4
Explanation: The somatic nervous system is formed by both the ramus dorsalis (dorsal root) and the ramus ventralis (ventral root), which are part of the spinal nerves responsible for voluntary movements and sensory perception.
11. Which of the following is not a function of parasympathetic nervous system ?
(1) Inhibition of peristalsis of alimentary canal
(2) Relaxation of arrector pilli muscles
(3) Erection of penis
(4) Contraction of urinary bladder
Answer: (1) Inhibition of peristalsis of the alimentary canal
Explanation: The parasympathetic nervous system promotes peristalsis (contractions) of the alimentary canal to aid in digestion. Inhibition of peristalsis would be a function of the sympathetic nervous system.
12. The function of cerebrospinal fluid surrounding CNS is to________
(1) Protect the brain from external jerks
(2) Provide nourishment and O2 to the brain
(3) Take away unwanted substances from the brain
(4) All of the above
Answer: (4) All of the above
Explanation: Cerebrospinal fluid (CSF) serves multiple functions, including protecting the brain from external jerks (cushioning), providing nourishment and oxygen to the brain, and removing waste products from the brain.
13. Small, solid and four optic lobes or colliculus called corpora quadrigemina are found in___________
(1) Mammals
(2) Amphibians
(3) Aves
(4) Reptiles
Answer: (1) Mammals
Explanation: The corpora quadrigemina, which consists of four rounded elevations, are found in the midbrain of mammals and play a role in visual and auditory reflexes.
14. Hypothalamus is situated on the________
(1) Upper lateral surface of diencephalon
(2) Lower lateral surface of diencephalon
(3) Ventral side of optic lobes
(4) Dorsal side of optic lobes
Answer: (2) Lower lateral surface of the diencephalon
Explanation: The hypothalamus is located on the lower lateral surface of the diencephalon and plays a vital role in regulating various physiological functions, including temperature, hunger, thirst, and hormone secretion.
15. Grey matter includes__________
(1) Concentrated cell body
(2) Unmyelinated axon
(3) Myelinated axon
(4) (1) & (2) both
Answer: (4) Concentrated cell body and unmyelinated axon
Explanation: Grey matter consists of cell bodies, dendrites, and unmyelinated axons of neurons. It appears grey due to the absence of myelin.
16. The layer of cells that covers the cerebral hemisphere is called_________
(1) Piamater
(2) Dura mater
(3) Cerebral cortex
(4) Both (1) & (2)
Answer: (3) Cerebral cortex
Explanation: The cerebral cortex is the outer layer of the cerebral hemispheres and is composed of grey matter. It plays a key role in memory, perception, and voluntary movement.

(4) All of these
Answer: (3) Limbic lobe
Explanation: The limbic lobe, part of the limbic system, is responsible for regulating emotions and motivations. Structures within the limbic lobe include the amygdala and hippocampus.
18. Which of the following contains a number of centers which control body temperature urge for eating and drinking?
(1) Thalamus
(2) Medulla oblongata
(3) Hypothalamus
(4) Cerebrum
Answer: (3) Hypothalamus
Explanation: The hypothalamus, located below the thalamus, contains several nuclei that regulate autonomic functions, including body temperature, hunger, thirst, and hormonal secretions.
