Neurons and Glia Flashcards
1
Q
structural organisation of the nervous system
A
- central nervous system
- peripheral nervous system (including enteric nervous system)
2
Q
functional organisation of the nervous system
A
- sensory
- somatic motor
- autonomic (sympathetic and parasympathetic)
3
Q
organisation of the nervous system by cell type
A
- nervous system is composed of neurons and glial cells
4
Q
neuron cell body function
A
- integrates signals from dendrites
- controls protein synthesis
5
Q
neuron axon function
A
- transmits signals in a binary (all or nothing) manner
- may be myelinated
- neurotransmitters released from presynaptic terminals
6
Q
axon hillock location and function
A
- at the start of the axon connected to cell body
- site of action potential initiation
7
Q
neuron dendrites appearance
A
extensively branched, often with spines
8
Q
dendrite function
A
- express receptors on postsynaptic membrane
- receive synaptic inputs from other neurons
- transmits electrical signals from synapse to cell body (graded potentials)
9
Q
express receptors meaning
A
a sensory nerve ending that changes specific stimuli into nerve impulses
10
Q
A
