25
is a combination of an electrical charge and a chemical reaction. It is not a flow of electricity, but an electrochemical signal moving along a neuron
NERVE IMPULSE
26
cannot jump from one neuron to another
NERVE IMPULSE
27
- When a nerve impulse comes to the end of an axon, it produces the chemical, called neurotransmitter, to be released. The chemical crosses the space between neurons called synapse and stimulates the nerve impulse to start in the next dendrite
NERVE IMPULSE
28
When a nerve impulse comes to the end of an axon, it produces the chemical, called n________-, to be released. The chemical crosses the space between neurons called ________and stimulates the nerve impulse to start in the next dendrite
NEUROTRANSMITTER, SYNAPSE
29
(plural: stimuli) is any factor in the environment that may trigger a nerve impulse
STIMULUS
30
is a reaction to a stimulus.
RESPONSE
31
A _______ is received by the body and a response is made. An organism must be able to respond to a stimulus in order to survive
STIMULUS
32
is the length of time between application of a stimulus and detection of a response.
REACTION TIME
33
transmit impulses from the brain to muscles, glands, or other neurons in the Peripheral Nervous System (PNS).
MOTOR NEURONS
34
transmit impulses from sensory nerves (receptor cells) to the Central Nervous System (CNS).
SENSORY NEURONS
35
MUTATION MAY INDUCED BY FACTORS CALLED?
MUTAGENS
