Q

Autonomic Nervous System is made up of two parts. What are they and what do they do?

A

The sympathetic Nervous system - Prepares the body for rigorous activity by increasing heartbeat, inhibiting digestion, and opening airways.

The parasympathetic nervous system - Dominant during relaxed states and decreases heartbeat, stimulates digestion , and closes airways.

Q

Cerebellum

A

Balance & cognintion

19
Q

Pons

A

source of many cranial nerves

20
Q

Medulla

A

Transition from brain to spinal cord. Regulates heart rate and cranial nerves.

21
Q

Cerebral Spinal Fluid

A
  • Ventricular System
  • Shock absorber
  • Nutrients and signaling chemicals
22
Q

Choroid Phexus

A
  • Produces CSF

- Lines the lateral ventricles

23
Q

How many glial cells will you find in the CNS?

A

Three: Oligodendrocytes, Astrocytes, and Microglial cells

24
Q

What is an Oligodendrocyte?

A

A type of glial cell that makes myelin.

25
Q

What is an astrocyte?

A

A type of glial cell that helps form the blood-brain barrier, break down certain neurotransmitters, and responds to injury.

26
Q

What is a Microglial cell?

A

A type of glial cell that removes cellular waste and can release chemicals that either promote or reduce inflammation.

27
Q

What is the autonomic nervous system?

A

It controls involuntary movements. Ex: heartbeat

28
Q

What are the cerebral hemispheres and what do they do?

A

Frontal - (Front of the brain) cognitive functioning and movement.
Parietal - (middle top of the brain) touch, sensation, orientation.
Occipital - (back of the brain) controls vision
Temporal - (bottom front of the brain) language and audition, speech

29
Q

What is the Cerebral cortex?

A

The surface of the brain

30
Q

What is Gyri?

A

The Ridges of the brain

31
Q

What is Sulci?

A

The crevices of the brain.

32
Q

What does the Cerebellum do?

A

Facilitates balance and timing of movement. balance and cognition.

33
Q

What is the Boca’s area?

A

It helps us to form our words

34
Q

What is Wrenicke’s area?

A

In temporal lobe and processes understanding of language.

35
Q

What is the Corpus Callosum?

A

It helps to connect the two hemispheres and helps them to understand each other

36
Q

Gray matter vs. White matter?

A

Gray matter = Where cell bodies lie

White matter = Pathways in the brain

37
Q

What is the Basal Ganglia?

A

Helps with movement. Is made of three parts: caudate nucleus, putamen, globus pallidus

38
Q

What is the Limbic System?

A

Helps with emotion and learning. Made up of: Amygdala, hippocampus, fornix, cingulate gyrus, olfactory bulb, hypothalamus

39
Q

The hippocampus is used for…

A

Long term memory

40
Q

What is the Thalmus?

A

Relay station - Routes info from the body to appropriate lobes. The info has to come here first.

41
Q

Hypothalamus

A

In control of vital functions such as: hunger, thrist, temp regulation, & sex

42
Q

Mid brain structures:

A
  • Superior colliculi = vision
  • Inferior colliculi = hearing
  • Substantia nigra = movement
  • Reticular formation = sleep/wave & consciousness
43
Q

Parts near the brain stem:

A
  • Cerebellum = balance & cognition
  • Pons = source of many crainal nerves
  • Medulla = Transition from brain to spinal cord, heart rate, & cranial nerves
