Neuron Basics
What part of the neuron receives incoming signals
Dendrites
What type of neuron carries information FROM receptors to the CNS
Sensory neuron
The brain and the spinal cord make up this system
This part of the brain controls balance and coordination
Cerebellum
This is the nervous systems primary job
Communication
What part of the neuron carries the signal away from the cell body
Axon
What type of neuron carries information FROM the CNS to muscles
Motor neuron
All nerves outside of the CNS belong to this system
Peripheral Nervous System
This lobe is primarily responsible for vision
Occipital Lobe
Which step of nervous system processing occurs when heat receptors in your skin detect a hot stove and send a signal to the spinal cord?
Sensory input
What structure speeds up nerve impulse transmission
Myelin sheath
These neurons connect sensory and motor neurons within the CNS
Interneurons
The division of the PNS that controls voluntary movement
Somatic nervous system
Which gland produces melatonin, regulating the sleep-wake cycle
Pineal Gland
When motor neurons carry a signal to the arm muscles to pull your hand away from a hot stove, which step is this?
Motor Output
What gap/junction exists between two neurons
synapse
Sensory neurons are structurally ____________.
Unipolar
This division controls involuntary actions like heart rate and digestion
Autonomic Nervous system
Describe one consequence if damage was done to the Parietal Lobe
unable to regulate emotions
Increased heart rate, dilated pupils, and slowed digestion indicate activation of this system.
Sympathetic
This part releases neurotransmitters into the synapse
axon terminal
Damage to this type of neuron would most directly affect movement
Motor neuron
Name the two branches of the Autonomic Nervous System and their functions.
Parasympathetic- "Rest and Digest"
Sympathetic- "Fight or Flight"
Which lobe is primarily responsible for your decision to wear gray today?
Frontal Lobe- decision making
The nervous system helps maintain this (balance) by detecting changes and coordinating responses to keep internal conditions stable.
Homeostasis
