Most neurons follow the same general structural plan, but the structure of individual neurons varies and is adapted to the specific function a given neuron (or class of neurons) needs to carry out.

Neurons receive excitatory or inhibitory input from other cells or from physical stimuli like odorant molecules in the nose. Input information usually comes in through the dendrites.

This video introduces the structure and structural types of neurons. Explore the structure of neurons, their types, and functions. Uncover the roles of dendrites, axons, and the soma. Learn about the …

Neurons (or nerve cells) are specialized cells that transmit and receive electrical signals in the body. Neurons are composed of three main parts: dendrites, a cell body, and an axon.

How neurons communicate with each other at synapses. Chemical vs. electrical synapses.

Wait. So how do the dendrites even respond to a signal. and what would be the defintion of a signal if you are dealing with neurons?

Given two points on a line, we can write an equation for that line by finding the slope between those points, then solving for the y-intercept in the slope-intercept equation y=mx+b. In this example, we …

Chemicals called neurotransmitters transfer information between two neurons separated by a gap. These chemicals pass the information from axon terminal of the first neuron to the dendritic tip of …

The organization of upper motor neurons (UMNs), lower motor neurons (LMNs), and sensory neurons creates a feedback system that modulates the strength of muscle contraction, maintains passive …
