Bain Anatomy

Front 1

The first cranial nerve is a sensory nerve consisting of thin fibers running from the olfactory mucosa to olfactory bulb

Back 1

olfactory nerver

Front 2

Destruction of this nerve results in inability to detect odors

Back 2

olfactory nerve

Front 3

the second cranial nerve is a sensory nerve which carried information about the visual world from the eye to the brain

Back 3

optic nerve

Front 4

This nerve forms a chiasma at the base of the brain

Back 4

optic nerve

Front 5

In the ________ some of the fibres from the left eye cross to the right eye of the brain and some of the fibres do not cross in this way

Back 5

optic chiasma

Front 6

Damage to this tract causes partial blindness in both eyes

Back 6

Optic Tract

Front 7

Damage to these nerve fibres between the retina and the optic chiasma cause blindness in one eye

Back 7

Optic Nerve

Front 8

Once the optic nerve fibres go caudal (below) the optic chiasma, they are referred to as this

Back 8

Optic Tract

Front 9

A motor nerve some of whose fibres control the activity of muscles that turn the eyeball in its socket.

Back 9

oculormotor nerve

Front 10

APs passing outward in others of the fibres of the third nerve cause (via a synapse and a second neuron) the pupils of the eye to ________

Back 10

constrict

Front 11

this happens to the pupils whenever the eye is exposed to a bright light

Back 11

constriction

Front 12

Fibers of this nerve also control a tiny muscle which changes the shape of the lens in order to focus sharply the images of objects located at various distances from the eye

Back 12

Oculomotor nerve

Front 13

This nerve shares with the oculomotor and abducens nerves the function of controlling the extraocular muscles

Back 13

trochlear nerve

Front 14

This nerve is not visible on the ventral surface of the brain but can be found emerging just behind the inferior colliculus

Back 14

trochlear nerve

Front 15

This nerve contains both sensory and motor fibers

Back 15

trigeminal nerve

Front 16

the main portion of this nerve, which is split into three divisions, carries sensory information from the skin, muscles, and other structures of the head such as the bones and teeth

Back 16

trigeminal nerve

Front 17

a dentist can reduce or abolish the pain produced by drilling in teeth by injecting a local anesthetic into the vicinity of branches of this nerve

Back 17

trigeminal nerve

Front 18

This type of drug blocks the passage of nerve impulses

Back 18

local anestetics

Front 19

the sensory branches of this nerve includes a motor nerve which runs to the jaw muscles to control biting and chewing

Back 19

trigeminal nerve

Front 20

This is a pure motor nerve which together with the oculomotor and the trochlear nerves, controls, the movements of the eye

Back 20

Abducens

Front 21

This is a mixed nerve, carrying sensory fibres for taste from the tongue as well as motor fibers to the muscles of the face

Back 21

facial nerve

Front 22

movements such as winking or smiling depend upon this nerve being intact

Back 22

facial nerve

Front 23

other motor fibres run to the salivary glands and tear glands to produce, respectively, salvation and the secretion of tears in this nerve

Back 23

facial nerve
