Document Summary
Identify the functions parts of the neuron: nissl bodies, axon hillock, axon, dendrites, telodendria, synaptic terminals, axolemma and axoplasm. Nissl body: acts as free ribosomes and rough er. Axon hillock: where action potential is initiated by voltage-gated channels, connects cell body to axon. Axon: is what sends signal to dendrites, can be myelinated or unmyelinated (in. Schwann cells all pns axons) and can be myelinated in oligodendrytes (in cns), makes up nerves, makes up white matter in brain, has mitochondria, has 2 types of transport. Dendrites: receives input from another neuron, usually attached to cell body. Synaptic terminals: where neurotransmitters are released, also called synaptic bulbs. Identify the roles of each type of neuroglia. Does mitosis occur in the neuroglia? capable of mitosis/regeneration. 6 types total (4 in cns, 2 in pns: cns. Ependymal: helps produce and maintain cerebrospinal fluid: pns. Schwann: myelinates all pns axons (can either be myelinated or unmyelinated depending on coverage)
