RUBBER BRAIN MODEL (copy)

1

parietal lobe, processes sensory information

2

precentral gyrus, voluntary skeletal muscle control

3

frontal lobe, complex reasoning

4

central sulcus, separates frontal lobe from parietal lobe

5

temporal lobe, processes auditory information

6

postcentral gyrus, processes sensory information

7

occipital lobe, processes visual information

1

corpus callosum, allows communication between cerebral hemispheres

2

choroid plexus, makes CSF

3

pineal gland, produces melatonin

4

corpora quadrigemina, contains visual and auditory reflex center

5

cerebral aqueduct, takes CSF from third to fourth ventricle

6

mammillary body, relay station for olfaction

7

intermediate mass of thalamus, connects thalamic lobes

8

pituitary gland, produces hormones

9

hypothalamus, drives (sex, hunger, thirst)

10

anterior commissure, allows communication between cerebral hemispheres

11

thalamus, relay station for sensation except smell

12

septum pellucidum, separates lateral ventricles

13

cerebral hemisphere, complex reasoning

14

fornix, concerned with olfaction

1

arbor vitae, conducts impulses concerned with equilibrium

2

vermis, coordinates posture and trunk movements

3

fourth ventricle, takes CSF from cerebral aqueduct to central canal

4

pons, connects brain with lower CNS centers

5

mammillary body, relay station for olfaction

8

olfactory bulb, houses synapses of olfactory nerve fibers, CN1, olfaction

Ⅰ

olfactory nerve, CN1, olfaction

ⅠⅠ

optic nerve, CN2, vision

What’s highlighted?

optic tract, carries visual impulses from optic chiasma that ultimately end up in visual cortex

What’s highlighted?

olfactory tract, carries impulses associated with sense of smell to brain

33

cerebral peduncle, connects cerebrum to pons

ⅠⅠⅠ

oculomotor nerve, CN3, eye muscle control

36

pons, connects brain with lower CNS centers

Ⅳ

trochlear nerve, CN4, eye muscle control

Ⅴ

trigeminal nerve, CN5, motor control of jaw muscles

Ⅵ

abducens nerve, CN6, eye muscle control

Ⅶ

facial nerve, CN7, facial expression

Ⅷ

vestibulocochlear nerve, CN8, hearing

Ⅸ

glossopharyngeal nerve, CN9, swallowing

Ⅹ

vagus nerve, CN10, parasympathetic control of heart, lungs, digestive tract

Ⅺ

accessory nerve, CN11, head and shoulder movement via sternocleidomastoid and trapezius

Ⅻ

hypoglossal nerve, CN12, tongue movement

39

medulla oblongata, controls vital autonomic functions like heart rate

37

spinal cord, reflex area

40

cervical nerve 1, head and neck movement
