Brain stuff

Question 1

Somatic

Answer 1

Voluntary movement like connecting messages

Question 2

Automatic

Answer 2

involuntary movement

Question 3

Occipital Lobe

Answer 3

Contains the primary visual cortex
Largely devoted to vision

Question 4

Temporal Lobe

Answer 4

Associated with hearing
Contains the primary cortex
Wemicke’s and Broca’s areas

Question 5

Parietal lobe

Answer 5

-Contains the primary somatic sensory cortex
-Responsible for attention and locating objects

Question 6

Frontal lobe

Answer 6

-For movement and planning
-Responsible for thought, planning, decision making and self control

Question 7

Brain hemispheres

Answer 7

Corpus callosum connects the spheres
The brain is contralateral

Question 8

Neuroplasticy

Answer 8

-The ability for the CNS to make adaptive changes to neuronal circuits
-The nervous system is more plastic when we’re developing

Question 9

Neurons

Answer 9

-Basic unit of nervous system
-Transmit info,to,from, within the central nervous system

Question 10

Gilas

Answer 10

-Support, nurture, and insulate neurons
-Removes debris
-Enhances the formation and maintenance of neuronal connections
-Modify neuronal functioning

Question 11

Resting Membrane Potential

Answer 11

-Neuron isn’t sending a message
-Inside is negatively charged
-Alot of potassium ions inside the cell and more sodium ions outside the cell
Sodium and Potassium pump allows movement across the membrane

Question 12

Threshold of Excitation

Answer 12

-Neurotransmitter message is received.
-Sodium gates along the membrane open and sodium rush in
-The cell becomes depolarized. If depolarization reaches a certain level then action potential will occur.

Question 13

Action Patential

Answer 13

-Messages get sent
-Electrical signal passes along the axon which causes the release of chemicals from terminal buttons.
-When a neuron fires, it fires with the same strength

Question 14

Neurotransmitters

Answer 14

-They reside in the terminal buttons of each neuron
-They’re released into the synapse and bind to specific receptors in the dendrites of the neighboring neurons.
-It can be terminated

Question 15

Reuptake

Answer 15

Nerotrans is re-absorbed back into terminals

Question 16

Degradation

Answer 16

Enzyme destroys neurotrans before binding

Question 17

Auto reception

Answer 17

Signals the presynaptic neuron to stop releasing

Question 18

Diffusion

Answer 18

Neurotans drift out of the synapse

Question 19

Inhibitory signal

Answer 19

Decreases the likelihood that the neuron will fire

Question 20

Excitatory Signal

Answer 20

Increases the likelihood that the neuron will fire

Question 21

Antagonists

Answer 21

Chemicals that inhibit the neurtrans influence

Question 22

Agonists

Answer 22

Chemicals that enhance the neurotran influence (like heroin)

Question 23

Sympathetic

Answer 23

types of automatic system
prepares the body for stress or action

Question 24

parasympathetic

Answer 24

type of automatic system
calms the body down
