patella ligament

2

monosynaptic ipsilateral

patella ligament

3

gyrus

elevated ridge

4

sulcus

shallow groove

5

fissure

deep groove

6

3 meninges

dura matter (outermost)
arachnoid mater
pia mater

7

olfactory nerve

smell

8

optic nerve

sight

9

oculomotor nerve

moves eyelid and eyeball and adjusts the pupil and lens of eye

10

trochlear nerve

moves eyeballs

11

trigeminal nerve

facial muscles include chewing (mastication)

12

abducens nerve

moves eyeballs

13

facial nerve

taste, tears, saliva, facial expressions

14

cerebral hemispheres

left and right

15

CNS

brain and spinal cord

16

PNS

cranial and spinal nerves, ganglia, sensory receptors

17

PNS divided into

sensory and motor

18

motor portion of PNS

somatic and autonomic

19

autonomic of PNS

sympathetic and parasympathetic

20

pineal body

secretes hormone melatonin

21

superior colliculi

visual reflexes

22

inferior colliculi

auditory reflexes

23

medulla oblongata

controls things we dont primarily control such as coughing, sneezing, blood pressure, blood vessel diameter, heart rate, breathing rate

24

pons

bridge connecting medulla and mesencephalon; work together to breathe for us; nuclei responsible for sleeping/waking

25

thalamus

gatekeeper; relays sensory information to cerebral cortex if necessary

26

pineal body

releases melatonin; regulates cyclic events; endocrine structure

27

hypothalamus

homeostasis; controls centers for thirst, rage, temp, hunger

28

cerebellum

place in space info; controls unconscious coordination of skeletal muscle

29

arbor vitae of cerebellum

white matter tracts in cerebellum; axons going up into cerebellum; tree of life

30

prefrontal cortex

conscious, self-awareness, personality

31

cortex

largest part of the human brain; associated with higher brain function such as thought or action

32

left cerebral hemisphere

language and cognitive processing

33

right cerebral hemisphere

creativity and expression

34

longitudinal fissure

divide the left and right cerebral hemispheres

35

central sulcus

separates the parietal lobe from the frontal lobe and also precentral and postcentral gyrus

36

postcentral gyrus

location of primary somatosensory cortex; receptive area for sense of touch

37

precentral gyrus

controls voluntary movements of skeletal muscles; cell bodies of pyramidal cell found here

38

occipital lobe

visual processing center

39

temporal lobe

primary auditory perception; hearing, smell taste

40

olfactory bulb

process all odors

41

olfactory tract

smell

42

optic nerve

transfer visual info from retina to vision center of brain

43

optic chiasma

where optic nerves cross to the opposite side of brain

44

optic tract

extends from optic chiasma to thalamus; for visual awareness

45

pituitary gland

center of endocrine system that secretes many hormones

46

mammillary body

reflex center for swallowing, chewing, eating; eating behavior in animals; relay/reflex center for olfaction

47

cerebral peduncles

conveys ascending and descending impulses to high or lower parts of the brain

48

corpus callosum

connects 2 cerebral hemispheres

49

lateral ventricle

receives CSF from choroid plexus; then fluid flows through interventricular foramen to 3rd ventricle

50

choroid plexus

masses of blood capilliries in brain ventricles that produce CSF

51

fornix

concerned with olfaction as well as limbic system

52

septum pellucidum

separates lateral ventricles

53

third ventricle

sends messages to and receives messages from the lateral ventricles and cerebral aqueduct

54

cerebral aqueduct

connects third and fourth ventricle

55

dura mater

thick outermost layer of meninges surrounding the brain and spinal cord

56

arachnoid mater

delicate weblike layer; middle layer

57

pia mater

thin delicate layer of meninges; innermost
