BIOL 1080 Lecture Notes - Lecture 7: Microglia, Central Nervous System, Glucose Transporter
Document Summary
The central nervous system : brain & spinal chord. The peripheral nervous system: somatic nervous system & autonomic nervous system. The endocrine system :endocrine system & exocrine system with endocrine-like activity. The local support and defense system: maintenance and support system, adaptation and repair system, resident defense system and migrant defense system. Peripheral : sensory input , motor output, can be voluntary of involuntary. Slide 3: 5 types of cns cells: neurons, oligodendrocytes (cns) and schwann cells (pns, astrocytes, microglia, ependymal cells. #2 to 5 are sometimes classified together as glial , or non-neuronal cells. Axon, dendrites, cell bodies, nodes of ranvier, schwann cells. Myelin sheaths allow for nerve impulses to travel much faster (ms is the deterioration or lack of this sheath) Nerve impulses are sent across the axon, with is released through the use of a neurotransmitter into the synaptic junction, where the neurotransmitter is released into the post synaptic membrane, where it is diffused.
