PCL102H1 Lecture Notes - Axon Hillock, Hindbrain, Unipolar Neuron
Document Summary
The neuron has the same basic characteristics of any eukaryotic single cell: nucleus, cytoplasm, cell membrane (not porous) Cytoplasm organelles: mitochondria (oxidative metabolism, rough endoplasmic reticulum with ribosomes (protein manufacture, smooth endoplasmic reticulum (fats, etc. , golgi apparatus simpler individual molecules, are assembled here, special form of smooth e. r. Some complex molecules, made up of: produces lysosomes: small sacs that contain enzymes that break down, cytoskeleton: thickest of the protein strands: microtubules. Interneurons are neurons located entirely within the central nervous system (i. e. they are not motor or sensory neurons). Local interneurons form circuits with nearby neurons and analyze small pieces of information. Relay interneurons connect circuits of local interneurons in one region of the brain with those in other regions. Terminal buttons need some items that can be produced only in the soma. There therefore needs to be a system that can transport these items rapidly and efficiently through the axoplasm (the cytoplasm of the axon)
