Answer 1

BIO PSYCHOLOGY DUH

Question 2

Explain Monism and Dualism

Answer 2

imong mama

Question 3

Also called nerve cells. Receive information and transmit it to other cells

Answer 3

Neurons

Question 4

Structure that protects the inside of the cell to the outside. thin and flexible barrier made of molecules that separates and encloses different parts of cells or compartments in living organisms, helping to control what goes in and out.

Answer 4

Membrane

Question 5

Branching fibers/roots of a neuron which impulses received from other cells at synapses are transmitted to the cell body.

Answer 5

Dendrites

Question 6

Cell body

Answer 6

Soma

Question 7

the long threadlike part of a nerve cell along which impulses are conducted from the cell body to other cells.

Answer 7

Axon

Question 8

Main working cells of the brain; support and nurture neurons.

Answer 8

Astrocytes

Question 9

Body’s defenders of the brain. Removes damaged cells; responds to pathogens

Answer 9

Microglia.

Question 10

type of glial cell that are involved in the formation of myelin sheath, insulators

Answer 10

Oligodendrocyte

Question 11

type of glial cell that surrounds neurons, keeping them alive and sometimes covering them with a myelin sheath, and are the major glial cell type in the peripheral nervous system

Answer 11

Schwaan cells

Question 12

type of glial cells that helps young braincells move to their right places as the brain grows

Answer 12

Radial Glia

Question 13

The ______ is like a protective shield made of special cells and structures that prevents harmful substances in the blood from easily entering the brain, while allowing essential nutrients and molecules to pass through to keep the brain healthy.

Answer 13

Blood-brain barrier

Question 14

________ surround brain capillaries and, during development, induce endothelial cells to form tight junctions. The endothelial tight junctions are the basis of the blood-brain barrier, a system of controlled transcapillary transport which maintains homeostasis in the CNS.

Answer 14

Astrocyte foot process

Question 15

quick electrical message that travels along nerve cells, allowing them to communicate and transmit information in the body.

Answer 15

action potential

Question 16

principle that states that the strength of a response of a nerve cell or muscle fiber is not dependent upon the strength of the stimulus. If a stimulus is above a certain threshold, a nerve or muscle fiber will fire

Answer 16

all or none law

Question 17

endings of a nerve cells that send signals to another nerve cell or muscle cells

Answer 17

presynaptic terminals

Question 18

block specific channels in nerve cells, called sodium channels. These channels are responsible for transmitting pain signals as electrical impulses

Answer 18

local anesthetic drug

Question 19

refers to the ability of the cell membrane to control the flow of substances in and out of the cell. It helps maintain a cell’s internal environment, and to regulate its internal conditions, such as osmotic pressure, pH, and ion concentration.

Answer 19

selective permeability

Question 20

Autonomic Nervous System consists of two divisions which are

Answer 20

Sympathetic and parasympathetic

Question 21

body’s “fight or flight” response, activating when you need to react quickly to a threat

Answer 21

sympathetic

Question 22

the “rest and digest” mode, helping your body relax and maintain normal functions during peaceful times.

Answer 22

parasympathetic

Question 23

Neurons/messengers that carry information from your body’s senses to your brain

Answer 23

Afferent neurons

Question 24

Neurons/messengers that transmit signals from your brain to your muscles and organs to control your body’s actions.

Answer 24

Efferent neurons

Question 25

the initial increase of the membrane potential to the value of the threshold potential. The threshold potential opens voltage-gated sodium channels and causes a large influx of sodium ions

Answer 25

hyperpolarization

Question 26

the interval of time during which a second action potential cannot be initiated, no matter how large a stimulus is repeatedly applied.

Answer 26

absolute refractory period

Question 27

the interval of time during which a second action potential can be initiated, but initiation will require a greater stimulus than before

Answer 27

relative refractory period (idk if apilon pani but whatevs)

Question 28

a sleeve that’s wrapped around each nerve cell (neurons). It’s a protective layer of fat (lipids) and protein that coats the main “body” section of a neuron called the axon

Answer 28

myelin sheath
