How do skeletal muscles help produce heat?
Give this one a try later!
keep body at 39C
What is the motor endplate?
,Give this one a try later!
part of the muscle cell that forms a synapse with the motor neuron. has
many chemically gated ion channels (ligand)
What is a sensory neuron?
Give this one a try later!
also known as afferent, conducts sensory input to the CNS
What is hemoglobin and why does it help determine skin color?
Give this one a try later!
oxygen-binding protein in red blood cells. the bright red color upon
binding oxygen gives blood vessel in dermis a red tint. those with fair skin
have more visibility of this red tint when the blood vessels dilate
What does the CNS consist of?
Give this one a try later!
brain and spinal cord
Describe blood vessels
,Give this one a try later!
arteries, veins, capillaries
explain epithelial tissue
Give this one a try later!
body surface area, inside hollow organs, many shapes and sizes
What is a motor neuron?
Give this one a try later!
also known as efferent, conduct motor output away from the CNS
What is the cell body (soma)?
Give this one a try later!
integrating center of neuron, recreates information, integrates it, and sends
response. The nucleus makes proteins
How do skeletal muscles help protect and support the body?
Give this one a try later!
, think abs and neck
What is sweat made of?
Give this one a try later!
urea, heavy metals, Na+,Cl-,electrolyte homeostasis
What is a threshold?
Give this one a try later!
the membrane potential needed to be reached for action potential to
occur
Explain the dermis layer
Give this one a try later!
Deeper than the epidermis, contains connective tissue, many different
proteins (collagen, elastic, reticular), blood vessels for thermoregulation,
sweat glands, sebaceous glands, nails roots, hair follicles. Also include
muscle (arrestor pili muscle) and a lot of nerve endings
Define muscle fatigue, and explain some of its causes.
