1
Q

Medulla oblongata

A

Reflexive, involuntary control of heart, breathing & blood vessels

2
Q

Pons

A

Timing of subconscious breathing

3
Q

Cerebellum (arbor vitae, vermis, L/R cerebellar hemispheres)

A

Subconscious control & coordination of voluntary muscle

4
Q

Midbrain (corpora quadrigemina, superior colliculi, inferior colliculi

A

Filter and relay visual (superior colliculi) & auditory stimuli (inferior colliculi); reflexive control of eye movement, focusing lens and pupil diameter

5
Q

Hypothalamus (mammillary bodies)

A

Control of ANS & pituitary gland and thereby, regulates involuntary body functions, homeostasis

6
Q

Thalamus (interthalamic adhesion = intermediate mass)

A

Crude perception of sensations & emotions and relaying afferent/efferent impulses to/from the cerebrum

7
Q

Pineal Gland

A

Endocrine gland - Secretes melatonin

8
Q

Pituitary Gland

A

Endocrine gland - Secretes hormones ACTH, growth hormone, LH, FSH, prolactin & TSH

9
Q

Infundibulum

A

Transport of hormones & conduction of impulses from hypothalamus to pituitary gland

10
Q

Cerebrum (cerebral cortex, cerebral tracts/white matter, fornix)

A

Will (choice), intelligence, memory, awareness, personality

11
Q

Longitudinal fissure

A

Divides cerebrum into cerebral hemispheres

12
Q

Left cerebral hemisphere

A

Dominates in speech sound & in understanding sequential, rational & analytical concepts

13
Q

Right cerebral hemisphere

A

Dominates in non-speech sounds (melodies, laughing, etc.), in spatial perception & in holistic, artistic & emotional concepts

14
Q

Frontal lobe

A

Voluntary control over muscles, learning, planning, higher psychological functions

15
Q

Parietal lobe

A

Perception of sensations of touch, temp, taste & body position (kinesthetic sensation)

16
Q

Temporal lobe

A

Perception of auditory sensation & related speech centers

17
Q

Occipital lobe

A

Perception of visual sensations

18
Q

Corpus callosum & anterior commissure

A

Communication between the two cerebral hemispheres

19
Q

Gyri & Sulci

A

Increase surface area of cerebrum for exchange of nutrients/wastes to/from blood vessels in the pia mater
