Q

Ventricles

A

Hollow chambers

17
Q

Ventricles contain

A

Cerebrospinal fluid(CSF)

18
Q

Choroid plexus

A

Create CSF that runs down, protects, and surrounds spinal cord

19
Q

Thalamus

A

Relay station for sensory info moving up, impulses to cortex for localization and interpretation, something good or bad

20
Q

Hypothalamus

A

Autonomic NS, center under thalamus

21
Q

Hypothalamus functions(6)

A

Regulate body temp, water balance, metabolism, limbo system, pituitary gland(hormones) & mammillary bodies(olfaction)

22
Q

Epithalamus

A

Pineal body(melatonin for sleep), choroid plexus

23
Q

Brain stems(parts& is)

A

Brain to spinal cord,

“Midbrain, pons, medulla oblongata

24
Q

Midbrain

A

Nerve fiber tracts

25
Q

Midbrain(parts)

A 
Cerebral peduncles(two bulging tracts convey messages as a push),
Corpora quadrigemina(four rounded protrusions pairs, reflex for vision and hearing)
26
Q

Pons

A

Middle, bulging part, center includes nuclei used for breathing

27
Q

Medulla oblongata

A

Lowest, connects spinal cord connect to Fiber facts to control visceral organs/; most effected by alcohol poisoning

28
Q

Medulla oblongata(controls)

A

Breathing, vomitting, swallowing, blood pressure regulation

29
Q

Medulla oblongata(extra)

A

Reticular formation, areas of grey matter

30
Q

Cerebellum

A

2 hemispheres- white & grey(Gyri/Sulci), involuntary coordination of body movement, timonging fir skeletal muscles; balance & equilibrium

31
