test 1 Flashcards
The key molecule responsible for release of neurotransmitter from a presynaptic vesicle as well as for activating and mobilizing astrocytes in the face of neuroinflammation:
calcium
Conveys information from sensory receptors into the central nervous system (CNS) and from the CNS to skeletal muscles, smooth muscles, and glands.
peripheral
Conveys information between the cerebrum and spinal cord. Is the region of sensory and motor integration and controls vital functions.
brainstem
_____________ axons carry information from peripheral receptors toward the central nervous system; _____________ axons carry information away from the central nervous system.
afferent; efferent
Cells that receive and transmit information via propagation of an electrical signal
neuron
The response of excitable tissue to stimulation either sensory, chemical or electrical, propagated down
the length of the axon is:
Local potentials are:
Synaptic receptors that respond to neurotransmitters bonding to them:
voltage gated
The portion of the Nervous System that is encased in bone:
cns
Generally, receptors respond to a sensory stimulus such as touch or temperature by opening a _________gated channel:
modality gated channel
_________________is the proportion of a population that develops a new case of the disorder whereas ____________is the current proportion of the population with the condition, including the both old and new cases.
incidence; prevalence
“I woke up this morning with a sharp pain running down the back of my left leg; yesterday I was fine….”
acute
“I’ve been having a little trouble with coordination in my right leg over the past several months.”
chronic
“For 3 days now, I’ve had brief spells of dizziness and felt like I was about to fall.”
subacute
Cells in the peripheral nervous system that produce myelin and NGF
schwann cells
. Cells in the central nervous system (CNS) with nutritive and clean-up functions and also have a role in neuroplasticity
astrocytes
