cow eye and sheep brain

pituitary gland

olfactor tract (cn 1)

optic chiasm (CN 2)

Right and left cerebral hemisphere

separated by longitudinal fissure

corpus callosum

mass of transverse fibers, connects 2 hemispheres

frontal lobe

judgement, concentration, and foresight (ability to think before acting); personality

1- olfactory

sense of smell

2- optic nerve

sense of vision

3- oculomotor

motor control eye movement

4- trochlear

motor nerve to one eye muscle

5- trigeminal

sensation of cornea, scalp, forehead, face, and teeth; motor to muscles of mastication

6- abducens

motor nerve to one eye muscle

7- facial

motor to muscles of facial expression; tatse from anterior 2/3 of tongue

precentral gyrus

primary somatic motor corte

parietal lobe

logical reasoning (math, problem solving) understanding speech

post central gyrus

primary somatic sensory cortex

temporal lobe

interpret and store auditory and olfactory sensations; understanding speech

occipital lobe

perception of visual stimuli

central sulcus

separate front lobe from parietal lobe

lateral sulcus (fissure)

separates frontal and parietal lobe from temporal lobe

pineal gland

secretes melatonin which plays role in circadian rhythm

t

thalamaus

relay center for all sensory information coming into brain (except olfactory); information filter

third ventricle

part of thalamus

hypothalamus

regulates body temp, hunger, thirst, sleep, sex, and emotional master endocrine gland

cerebral aqueduct- part of brain stem, specifically midbrain

passageway connecting 3rd and 4th ventricles

superior colliculi- part of brain stem, specifically midbrain

visual reflex center

inferior colliculi- part of brain stem, specifically midbrain

auditory reflex center

cerebral peduncle- part of brain stem, specifically midbrain

motor tracts decend from primary motor cortex through these to spinal cord

pons

bridge connecting cerebrum to cerebellum

fourth ventricle

medulla oblongata

regulation center for respiration and cardiac function

cerebellum (little brain)

regulation of muscle tone, coordination of motor activity and maintanence of balance and equilibrium

part of cerebellum know where these are

right and left cerebellar hemispheres

vermis

arbor vitae- white matter of little brain

folia- folds in brain

ventricles of brain

lateral ventricle

interventricular foramen

third ventricle- with interthalamic adhesion

cerebral aqueduct

fourth ventircle- diamond shpaed ventirlce located anterior to cerebellum

central canal (of spinal cord)

choroid plexus- tissue that manufacture CSF

cerebrum

pineal gland

cerebellum

superior colliculus

inferior colliculus

infundibulu,

cerebral peduncles

medulla oblongata

spinal chord

pons

Cranial nerve 1-7

fibrous tunic

1. cornea

2. sclera

vascular tunic

1. choroid

2. ciliary body

3. iris

4. pupil

retina

lens

optic nerve (cn 2)

cavities of eye

1. anterior cavity-has aqueous humor

2. anterior chamber

3. posterior chamber

4. posterior cavity
