Week 1 Terms

Question 1

Planes: Sagital

Answer 1

Left/Right

Question 2

Mylineation

Answer 2

When myelination is present, the axon propogates their signal faster

Question 3

Left hemisphere

Answer 3

verbal memory, creativity, artistic, abstract

Question 4

Right hemisphere

Answer 4

Organization, planning, rules

Question 5

Cerebellum

Answer 5

“The little brain”, located in the back of the brain and responsible for sensory, motor, balance/coordination, memory, learning, emotion

Question 6

Lobes: Frontal Lobe

Answer 6

problem solving, organization, inhibition, planning

Question 7

Lobes: Temporal

Answer 7

Contains the limbic cortex, amygdala, and hippocampal formation; processing auditory information, affect, memory, and recognition (Left: verbal, right: nonverbal)

Question 8

Lobes: Occipital

Answer 8

Near the back of the brain, responsible for vision (most specialized part of the brain)

Question 9

Lobes: Parietal

Answer 9

Processes somatosensory information (speech, pain, spatial orientation)

Question 10

Meninges

Answer 10

Contains: dura, arachnoid membrane, and pia mater; located between the skull and the brain; primary function is to help protect the brain

Question 11

Cerebral Spinal Fluid: purpose

Answer 11

provides cushioning for the brain

Question 12

Cerebral Spinal Fluid: the process of creation, flow and reabsorption

Answer 12

produced in the ventricles; fills the subarachnoid space, canal of spinal cord, and the cerebral ventricles

Question 13

Blood brain barrier: cells involved

Answer 13

tight juncture of endothelial cells (and astrocyte feet)

Question 14

Blood brain barrier: purpose

Answer 14

blocks toxins and bacteria while allowing the passage of water, some gases, and lipid-soluble molecules by passive diffusion; as well as the selective transport of molecules such as glucose and amino acids that are crucial to neural functions

Question 15

Nervous System Schematic

Answer 15

Nervous system—

• Central
• -Brain
• -Spinal Cord
• Peripheral
• -Autonomic
• –Sympathetic
• –Parasympathetic
• -Somatic

Question 16

Central nervous system

Answer 16

Made up of the brain and spinal cord

Question 17

Peripheral nervous system

Answer 17

Everything else! Made up of two parts: autonomic (fight/flight freeze or relaxation) and somatic (senses)

Question 18

Autonomic

Answer 18

Contains the sympathetic system (responsible for fight or flight) and the parasympathetic system

Question 19

Sympathetic

Answer 19

Responsible for reacting to stress and engages the fight or flight response to maintain safety.

Responses include: breathing and heartbeat are faster, blood pressure rises, muscles tense, hands and feet are cold and sweaty, mouth becomes dry

Question 20

Parasympathetic

Answer 20

Responsible for relaxation, digestion, maintaining homeostasis, breathing

Question 21

Somatic

Answer 21

Part of the peripheral nervous system responsible for the five senses

Question 22

Circle of willis

Answer 22

A loop of connected blood vessels at the base of the brain that is responsible for supplying blood to the brain. Looping pattern serves a protective role and if there is damage to part of it, the blood can still get to all parts of the brain (it would just be slower)
