⫸ 3 Parts of a Neuron. Ans: cell body, dendrites, axon
⫸ Nucleus. Ans: Control center of the cell
⫸ Organelle. Ans: A tiny cell structure that carries out a specific
function within the cell
⫸ Mitochondria. Ans: Powerhouse of the cell - create energy for the
cell
⫸ Effector Site. Ans: A part of the body that received info from
neurons (muscles, organs)
⫸ Electrolytes. Ans: Minerals that have an electrical charge to help
transmit nerve impulses throughout the body, such as sodium,
potassium, and magnesium.
⫸ Axon. Ans: is a cylindrical projection extending from the cell body
that carries nerve messages
,⫸ Dendrites. Ans: structures that receive messages from other
neurons
⫸ 2 Parts of the Nervous System. Ans: central nervous system and
peripheral nervous system
⫸ Central Nervous System. Ans: A division of the nervous system
that includes the brain and spinal cord.
⫸ peripheral nervous system. Ans: Nerves that connect the rest of the
body to the central nervous system.
⫸ Afferent Pathway. Ans: Sensory pathway that relays information to
the central nervous system.
⫸ 2 Main Functions of Peripheral Nerves. Ans: 1. Provide sensory
info (sight, smell, touch, taste) 2. Relay info from CNS back down to
rest of body thru efferent pathway
⫸ Interneurons. Ans: Neurons located within the spinal cord and
brain that transmit impulses between afferent and efferent neurons.
⫸ Mechanoreceptors. Ans: Specialized structures that respond to
mechanical forces (touch and pressure) within tissues and then
transmit signals through sensory nerves.
, ⫸ Nociceptors. Ans: Pain receptors
⫸ Chemoreceptors. Ans: Respond to chemical interaction
(smell/taste)
⫸ Photoreceptors. Ans: Respond to light (vision)
⫸ Somatic Nervous System. Ans: Nerves that serve the outer areas of
the body and skeletal muscle and are largely responsible for the
voluntary control of movement.
⫸ Autonomic Nervous System. Ans: Runs the involuntary processes
of the body (e.g., circulating blood, digesting food, producing
hormones).
⫸ Sympathetic Nervous System. Ans: Increase neural activity and put
the body in a heightened state. )fight or flight)
⫸ Parasympathetic Nervous System. Ans: decreases neural activity
and put the body in a more relaxed state. (Rest & digest)
⫸ Sensory Function. Ans: Ability of the nervous system to sense
changes in either the internal or external environment.
⫸ Proprioception. Ans: Our sense of body position (not having to
look at hand placement when shooting a basketball)
