Grab bag
100
a cell that carries electrical and chemical signals through the nervous system
What is a neuron
100
senses perceived using specialized brain regions
What are special senses
100
an automatic response to a stimulus
What is a reflex
100
type of muscle tissue that is voluntarily controlled
What is skeletal muscle
100
when muscle twitches occur rapidly and don't allow any time for the muscle to relax
What is fused tetanus
200
resting state, depolarization, repolarizatiion, overshoot
What are the steps of an action potential
200
touch, temperature, nociception, proprioception
What are somatic senses
200
control by two opposing branches
What is antagonistic control
200
contains ATP and actin binding sites; makes up thick filaments
What is myosin
200
all sensory neurons have this to allow us to know where a stimulus is coming from
What is a receptive field
300
the time for Na+ channels to go from inactive to closed and they cannot re-open until they reset
What is the absolute refractory period
300
senses perceived through chemoreception
What are olfaction and gustation
300
a neuron that releases norepeniphrine on target tissues
What is sympathetic postganglionic neuron
300
thin and thick filaments slide across each other, which shortens the sarcomere but not the filaments themselves
What is the sliding filament model
300
a type of electrical signal that may either hyperpolarize or depolarize
What is a graded potential
400
when an AP reaches the axon terminal, the influx of Ca+ triggers this
What is neurotransmitter release
400
senses of the ear
What are hearing and equilibrium
400
the pathway in which there is a long preganglionic neuron and short postganglionic neuron
What is the parasympathetic pathway
400
the response of a single muscle fiber to a single AP
What is a muscle twitch
400
the regulation of stable conditions in the body's internal environment through negative feedback
What is homeostasis
500
graded potentials that result from neurotransmitter release
What is a post-synaptic potential
500
the sense perceived through photoreception
What is vision
500
the pathway that consists of one neuron connecting the CNS to the target tissue
What is a somatic motor pathway
500
actin-myosin interaction, pumping Ca2+ into the SR, restoring Na+ gradients
What are uses of ATP in muscle contraction
500
the neurotransmitter released by ANS preganglionic neurons and somatic motor neurons
What is acetylcholine
