CNS
This part of the CNS is responsible for basic life functions like breathing and heart rate
Brain stem
The PNS includes all nerves that lie outside of what system?
CNS
These receive incoming signals from other neurons.
Dendrites
The resting membrane potential of a neuron is
-70mV
This lobe is responsible for vision
Occipital Lobe
This structure connects the brain to the rest of the body and controls reflexes
Spinal cord
This division controls voluntary movements of skeletal muscles
Somatic NS
The part of the neuron that carries impulses away from the cell body are called
Axons
The rapid change of polarity across the membrane is called what?
Depolarization
This lobe is responsible for decision-making and personality
The largest part of the brain, responsible for thinking, memory, voluntary movement
Cerebrum
This division controls involuntary functions like digestion and heart rate.
Autonomic NS
This insulating layer increases the speed of nerve impulses.
The myelin sheath/Schwann cells
The movement of these ions into the cell causes depolarization
Na+
This lobe processes auditory information.
The temporal lobe.
The protective structure that surrounds the brain and spinal cord and contains cerebrospinal fluid
Meninges
This branch of the autonomic nervous system prepares the body for 'flight or fight'
Sympathetic NS
Gaps in the myelin sheath where action potentials fire are called
Nodes of Ranvier
The movement of these ions out of the cell causes repolarization
K+
This lobe processes touch, temperature, and pain.
This part of the brain coordinates balance, posture, and fine motor skills
Cerebellum
This branch of the autonomic NS promotes 'rest and reset'.
Parasympathetic NS
The region where neurotransmitters are released into from the axon terminus
the synaptic cleft/synapse/chemical synapse
The stimulus must breach this for an action potential to fire. State the voltage as well.
Threshold potential, -55mV
This system regulates emotions and memory.
The limbic system
