Bio E109 Midterm 1 Questions With Complete Solutions
Absolute refractory period Correct Answers Period of time
where the sodium channels cannot respond or reopen
Action potential is due to the... Correct Answers Depolarization
wave down the axon die to the channels opening and closing
Action potentials Correct Answers Depolarization waves
-dependent on voltage dependent channels
Active transport Correct Answers Needs energy to move
substance across gradient
Adrenal sympathetic pathway Correct Answers -arsenal glands
sit on top of the kidneys and interacted by parasympathetic pre
ganglion, release ACh and caused the release of adrenaline
Afferent nervous system Correct Answers Takes info from the
outside and. Brings to CNS
-mostly sensory neurons, has nerve endings and sensory portions
that are largely exterior
Antagonistic muscles Correct Answers Groups that move bones
in opposite directions
-muscle contraction can pull on a bone but cannot push a bone
away
,Autonomic nervous system Correct Answers Portion of the
body that controls portion of the body, not related to skeletal
muscles
Autonomic tissue targets Correct Answers -smooth and cardiac
muscles
-some endocrine and exocrine glands
-some adipose tissue from
Autonomic varicosities Correct Answers -release
neurotransmitters over the surface of target cells
-released over the surface of organs
Bipolar neuron Correct Answers Two processes, the axon and
dendrite
Blood plasma is composed of... Correct Answers Sodium
Chloride, bicarbonate
High protein
Ca movement in... Correct Answers Depolarization
Calcium is more concentrated in the.... Correct Answers
Outside of the cell, when calcium rushes in the cell there is a
huge gradient
Carriers Correct Answers Slower transport of larger molecules
Central nervous system Correct Answers Consists of the vein
and spinal cord
, Channels Correct Answers Rapid transport of small ions
Cl movement in Correct Answers Hyperpolarization
Cytoplasm is composed of... Correct Answers Potassium,
magnesium
Chloride, phosphate, anion
High protein content
Dorsal root Correct Answers Part of spinal cord up against the
back
-sensory and m
During contraction.. Correct Answers The sarcomere shortens
H zone and I band both shorten and the A band remains constant
Efferent nervous system Correct Answers Contains nerves that
have signals that run out and control the body
-some are somatic (body) neurons and motor (muscles) neurons
Electrochemical gradient Correct Answers The sum of these
two gradient of equilibrium
End muscle contraction Correct Answers Calcium removed
from cytoplasm and put back to cytoplasmic reticulum
Equilibrium Correct Answers Two forces are equal still have
chemical/electrical gradient and they are stable
Excitation-Contraction Coupling Correct Answers
