1 Flashcards
The nerve cell that carries impulses from a sense receptor to the brain or spinal cord.
Sensory neurons
The nerve cell that connects sensory and motor neurons.
Interneurons
The nerve cell that transmits impulses from the brain.
Motor neurons
Neurons found in the muscles or glands.
Motor neurons
long fiber that carries the nerve impulses
Axon
Fear center of the brain
Amygdala
connection between adjacent neurons
Synapse
The chemical secreted into the gap between neurons at a synapse.
Neurotransmitters
rapid automatic response to a stimulus.
Reflex
covering of fatty material that speeds up the passage of nerve impulses.
Myelin sheath
structure at the end of an axon that produces neurotransmitters to transmit the nerve impulse across the synapse
Axon terminal
The high speed signals that pass along the axons of nerve cells
Nerve impulse
branching filaments that conduct nerve impulses towards the cell
Dendrites
sense organ or cells that receive stimuli from outside the body
Sense receptor
reaction to a stimulus by a muscle or gland.
