Nervous System
Central Nervous System - ✔ CORRECT ANSWER ✓✓(CNS) brain and spinal cord.
Peripheral Nervous system - ✔ CORRECT ANSWER ✓✓Body Nerves that connect to the central
nervous system (brain and spinal cord). Connects the central nervous system to the body's
organs and limbs.
Autonomic Nervous System - ✔ CORRECT ANSWER ✓✓Controls involuntary bodily functions
(not consciously controlled), such as breathing, the heartbeat, and digestive processes
Somatic Nervous System - ✔ CORRECT ANSWER ✓✓Controls voluntary bodily functions
(consciously controlled), such as controlling skeletal muscles
2 Major Functions of Nervous System - ✔ CORRECT ANSWER ✓✓1. Sensory Reception-end of
peripheral neurons monitor conditions( light,sound,temperature)
2. Integrative Functions- Sensory messages that get sent repeatedly get remembered "motor
functions" (subconscious actions)
Order of Stimulus (from sensory to effector) - ✔ CORRECT ANSWER ✓✓1. Stimuli: physical or
chemical signal (ex. hot room)
2. Nerve impulse (ex. sends signal to brain)
3. Effectors: muscle & glands react (ex. sweat glands start sweating)
Stimulus - ✔ CORRECT ANSWER ✓✓Things that initiate nerve impulses (ex. hot room)
, Effector - ✔ CORRECT ANSWER ✓✓Response (ex. Sweating)
Motor Functions - ✔ CORRECT ANSWER ✓✓Complex muscle-and-nerve acts that produce
movement (walking, writing, typing running etc.)
"Electrochemical" - ✔ CORRECT ANSWER ✓✓A nerve impulse is partially electric (change in
polarity/charge) and partially chemical (neurotransmitters)
Synapse - ✔ CORRECT ANSWER ✓✓Where the nerve impulse is sent (connection of 2 neurons) .
Action Potential changes the charge of the synapse (causes electricity) and Neurotransmitters
are sent.
Myelin Sheath - ✔ CORRECT ANSWER ✓✓Covering of Schwann Cells, Speeds up nerve
impulses.
Axon - ✔ CORRECT ANSWER ✓✓The long threadlike part of a nerve cell that carry the nerve
impulse
Dendrites - ✔ CORRECT ANSWER ✓✓Branch like extensions on a neuron that GET signals and
connect to the synapse
Neurotransmitters - ✔ CORRECT ANSWER ✓✓Chemicals that transmit signals across a synapse
from one neuron to another 'target' neuron
Multipolar Neuron - ✔ CORRECT ANSWER ✓✓Most of the brain/spinal cord & is mylinated
Central Nervous System - ✔ CORRECT ANSWER ✓✓(CNS) brain and spinal cord.
