The Brain and Nervous System

Conducts action potentials from sensory receptors to the CNS

Conducts action potentials from the CNS to effector organs such as muscles and glands

Efferent subdivision which transmits action potentials from the CNS to the skeletal muscles

Efferent subdivision which transmits action potentials from the CNS to cardiac and smooth muscles

Prepares the person for physical activity

Activates function such as digestion or respiration

Rough ER concentration that appear as microscopic granules

Short extensions that function to recieve information from other neurons or receptors

A long cell process that transmits action potentials away from the CNS

Branch off the axon

have many dendrites and a single axon

one dendrite and one axon

a single process extending from the cell body

Nerve Glue (5 Types)

a type of neuroglia that serves as the major supporting tissue in the CNS

AStrocyes and the blood vessel endothelium form this permeability barrier

Specialized sheaths

Gaps in the myelin sheath, can be seen between oligodendrocyte and schwann cell segments

Groups of neuron cell bodies and their dendrites

Bundles of parallel axons with their myelin sheaths are whitish in color
