what is f

• nucleus

• axon

• cell body

what is h (meant to be g but blue box didnt cover h)

• nucleus

• dendrites

• node of ranveir

• axon

what is the myelin sheath

• fatty white substance found around the axon and made by schwann cells

• fatty white substance found around the schwann cells and made by the axon

• fatty white substance found around the schwann cells and made by the nucleus

• fatty white substance found around the schwann cells and made by the dendrites

function of the myelin sheath

• acts as an insulator

• speeds up conduction of action potentials

• provides protection and support to nervous tissues

• inulates the axon of neurons in the cns

what are the types of neurons

• sensory neuron

• interneuron

• motor neuron

• outerneuron
