Small Spaces between the myelin sheath covering the axons of neurons
Difference between gray and white matter in the brain. How does it relate to myelin sheaths?
Regions of the brain and spinal cord containg dense collections of myelinated fibers reffered to as white matter primarily fiber tracts. Gray matter contains mostly nerve cellbodies & unmyelinated fibers.
Direction of impulse conduction in a neuron
What structures make up the central nervous system
Brain & Spinal Cord
What structures make up the peripheal nervous system
Nerves & Ganglia that lie outside of the brain & spinal cord
Function of neurotransmitters
Open & Close ion channels that influence membrane permeability & consequently membrane potential
Difference between chemical synapse and electrical synapse
Electrical synapses specialized to allow the flow of ions between neurons. While chemical synapses are specialized to release reception of chemical neurotransmitters.
Layers of connective tissue
A large transient deplorazation event, including ploarity reversal thatis conducted along the membrane of a muscle cell or nerve fiber
Which ions move through stimulus gated channels?
Sodium and pottasium
What is the resting membrane potential of a neuron
What are the effectors of the somatic nervous system?
What are the effectors of the autonomic nervous system?
Nerves containg the process of motor and sensory neurons
Form Cerebrospinal fluid which fill cavaties and surrounds cushions
