What is the función of the labeled structures?
(it's a neuron)

A: Dendrites ~ reception

receive incoming A/P (from other neurons or sensory cells)

B: Axon ~ conduction

A/P waves propagate through axons, connecting neurons to other neurons (or to effector cells)

C: Terminals~ transmission

Synapses deliver neurotransmitters to other neurons (or to effector cells)

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
