Q

Left brain

17
Q

Right brain

A

Creative, think outside the box, emotional

18
Q

What connects the left and right brain?

A

Nothing except the brain stem

19
Q

Brain stem

A

Connects the cerebrum with the spinal cord

20
Q

Pons

A

Bridge where nerves cross over

21
Q

Mid brain

A

Passageway for electrical impulses

22
Q

Medulla oblongata

A

Vital functions (Respiratory rate, heart rate, blood pressure, and temp)

23
Q

Quiz yourself on where each part of the brainstem is

24
Q

Cerebellum

A

Controls balance and equilibrium. Provides precise timing for skeletal muscle. Coordination of body movements.

25
Spinal cord
Transmits nerve impulses between brain, limbs, and lower part of body. Protected by CSF and spinal column. Composed of neural tissue.
26
Protection of CNS
Scalp, skin, skull, vertebral column, meninges, CSF, blood-brain barrier.
27
Blood-brain barrier
"Filter". Filters blood from arteries that supply the brain to have extra security and cleanliness. Not fool proof
28
PNS functions and what it's composed of
Composed of 12 pairs of cranial nerves and 31 pairs of spinal nerves. Receives and transmits messages.
29
Afferent
Sensory info to the brain. Sensory nerves. Sends messages towards CNS
30
Efferent
Motor info out/away from the brain. Motor nerves. Receives messages from CNS.
31
Neuron
Basic cell of nervous system (singular nerve cell)
32
Cranial nerves
Nerves that connect the brain to mostly to cranial features
33
Spinal nerves
Nerves that branch off from the spinal cord.
