Answer 1

Central nervous system (CNS)

Question 2

It consists of paired olfactory lobes and the cerebral hemispheres

Answer 2

Telencephalon

Centers for association memory

Answer 3

Cerebral hemispheres

Question 4

This is located between the optic lobes and posterior to the cerebral hemispheres. It functions in balance, vision and spontaneous movement

Answer 4

Diencephalon

Question 5

Formed by the crossing fibers of the optic nerves

Answer 5

Optic chiasma

Question 6

This is the midbrain, which is the center for visual coordination

Answer 6

Mesencephalon

Question 7

The communication of optic ventricles with the third ventricle and fourth ventricle

Answer 7

Aqueduct of Sylvius

Question 8

This is the brain part that makes up the cerebellum. It functions in equilibrium and coordinated movements

Answer 8

Metencephalon

Question 9

The medulla oblongata is located in this brain part. It narrows towards the posterior end, forming the spinal cord

Answer 9

Myelencephalon

Question 10

It is mainly made up of nerves that extend from the brain and the spinal cord

Answer 10

Peripheral nervous system (PNS)

Question 11

It arises from the anterior end of olfactory lobe and innervates the cells of olfactory sac

Answer 11

Olfactory nerves

Question 12

Nerve fibers arise from the retina of the eye

Answer 12

Optic nerves

Question 13

It is a small nerve arising from the ventral side of the midbrain

Answer 13

Oculomotor nerves

Question 14

It is a small nerve arising from the dorsal side of the brain between the optic lobes and cerebellum

Answer 14

Trochlear nerves

Question 15

It is the largest of the cranial nerves arising from the sides of the anterior end of the medulla oblongata

Answer 15

Trigeminal nerves

Question 16

It arises from the ventral side of the medulla oblongata and enters the orbit and goes to the posterior rectus muscle of the eye ball

Answer 16

Abducens nerves

Question 17

It arises from the antero-lateral side of medulla oblongata posterior to the fifth cranial nerve

Answer 17

Facial nerves

Question 18

It arises from the anterior side of the medulla and are distributed to the inner ear

Answer 18

Auditory nerves

Question 19

It arises from the group of roots at the sides of the medulla

Answer 19

Glossopharyngeal nerves

Question 20

It has the same origin with the ninth cranial nerves. These innervate the shoulder muscles, larynx, esophagus, stomach, lungs and heart

Answer 20

Vagus nerves

Question 21

A white calcareous body which surrounds the dorsal ganglion

Answer 21

Gland of Swammerdam

Question 22

Innervates the tongue and hyoid muscles

Answer 22

First spinal nerve

Question 23

The biggest, receives branches from the first spinal nerve

Answer 23

Second spinal nerve

Question 24

Innervates the shoulder and forelimbs. This sends a branch to the second nerve and then branch off to the external oblique, transversus and skin

Answer 24

Third spinal nerve

Question 25

Distributed to the muscles and skin of the body wall

Answer 25

Fourth, fifth and sixth nerves

Question 26

Form the sciatic plexus, which innervates the hind limbs

Answer 26

Seventh, eight and ninth spinal nerves

Question 27

Innervates the urinary bladder and cloaca

Answer 27

Tenth spinal nerve
