Axons carry outgoing signals to the target Axons are for chemical and electrical signals - cytoplasm is filled w/ many types of fibers and filaments but lacks ribosomes and endoplasmic reticulum o proteins must first be synthesized on rough endoplasmic reticulum in cell body axonal transport: are used to move protein down to axon slow axonal transport: slow transports used for component that are not rapidly consumed by cell, such as enzymes and cytoskeleton proteins fast axonal transport: steps organelles in a stop-and-go fashion - goes in two directions: forward and backward - forward: moves synaptic and secretory vesicles and mitochondria from cell body to axon - backward: returns old cellular components from axon terminal to cell body for recycling Glial: Provide important physical and biochemical support to neurons - do not participate directly in transmission of electrical signals -communite primarily via chemical signals - help maintain neurons and guide them during repair and development
