4/23/24 quiz chapter 10

Question 1

3 types of neurons

Answer 1

motor, sensory, interneuron

Question 2

motor neuron structure and function

Answer 2

The effector/responder neuron that takes information from the CNS (by interneurons) to the muscle or gland that needs to respond. It has a dendrite, cell body, axon, and axon terminal.

Question 3

sensory neuron structure and function

Answer 3

receptor-detects info from sensory glands/organs and sends it to the CNS (through interneurons). The cell body is centrally located. less dendrites

Question 4

interneuron structure and function

Answer 4

bridge b/t sensory and motor, located in the CNS and spinal cord. They are shorter

Question 5

4 chamber of the heart

Answer 5

left/right atria, left/right ventricle

Question 6

atria

Answer 6

receives blood. The right receives blood from the body superior/inferior vena cava. left receives from pulmonary veins (?)

Question 7

ventricles

Answer 7

send out blood. right ventricle gets blood from the tricuspid valve (from the right atria) and sends it through the pulmonary semilunar valve to the arteries. Left ventricle gets blood from the mitral valve (from the left atrium) and goes to the aortic semilunar valve and aorta (vessel)

Question 8

our circulatory system is special because its a….

Answer 8

closed double loop

Question 9

deoxygenated and oxygenated blood flow

Answer 9

know the blood from the atria/ventricle question. blood is deoxygenated in the atria and oxygenated in the ventricle. Study blood flow through heart handout

Question 10

diffusion

Answer 10

uses small nonpolar particles in permeable membrane. Concentration goes high to low. Solute and solvent can move. no energy needed

Question 11

Osmosis

Answer 11

concentration high to low. only solvent can move. semipermeable membrane. no energy needed (passive transport)

Question 12

facilitated diffusion

Answer 12

concentration high to low. moves large polar molecules by protein channels. no energy needed with the concentration gradient

Question 13

active transport

Answer 13

concentration low to high-so requires energy bc active transport. requires ATP.
