Excitatory Synapse & Inhibitory Synapses - ️️In other words, it's not the neurotransmitter itself that is excitatory or Inhibitory, but rather the effect of that neurotransmitter that is excitatory or inhibitory at the receptor sites of a particular synapse. when the cell is semipermeable - ️️This means some substances that are outside the cell can enter through tiny protein openings, or channels, in the membrane, while other substances can go outside. Nervous System - ️️a ...

LIFSCI 7C XL - Animation: Hierarchical Organization of Muscle & Cross-Bridge Cycle Latest Update Graded A+ What is the primary role of the muscle spindle in the body? It detects changes in muscle length, helping regulate muscle contraction and maintain muscle tone. How does the spinal cord contribute to reflex actions without involving the brain? It acts as the processing center for reflex arcs, allowing for quick responses to stimuli without needing brain input. Why is a monosy...

When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end plate. - ANSWER TRUE Briefly explain why the action potential flows only from the axon hillock to the terminal web. - ANSWER During the course of an action potential there is a refractory period that makes sure the action potential can't trigger backwards by the use of caps on gated sodium channels. The caps close and keeps the action potential flowing in one direction. How do the glial cells (i.e., m...
