When neuron is sufficiently stimulated this process starts the movement of ions across the axon membrane?
Depolavization
What effect does an action potential have on a vesicle?
It causes the vesicles (which are in the axon terminal) to move to the cell membrane at the end of the axon terminal, where they merge with the cell membrane, releasing their load of neurotransmitters into the synaptic cleft (gap), where they quickly diffuse to receptors in the post-synapticneuron's dendrites, initiating a graded potential which moves down the dendrites, along the soma,to the axon hillock where it can cause an action potential in that secondneuron.
When an action potential is initiated on a nerve cell membrane it radiates and is propagated in all directions from the point of initial stimulation?
Correct. The action potential is initiated at a specific point on the cell membrane called the axon hillock, and it then travels down the axon in one direction. Once initiated, it spreads along the entire length of the axon and can be transmitted to other neurons or muscle cells.
What cell organelles are used to allow the dendrite to function?
Cell membrane, Nucleus, Cell wall, and axon terminal
What is the brief period during which a local area of an axon's membrane resists stimulation called?
That is called the refractory period.
What is a axon hillock?
An axon hillock is a special cell body that connects an axon to a neuron. It is the last place where propagated membrane potentials are transmitted to the axon.
What is an axolemma?
An axolemma is the surface membrane of an axon.
What is axolemma?
An axolemma is the surface membrane of an axon.
Electrical change in the neuronal membrane that is transmitted along axon is?
Action potential is the term for an electrical change in the neuronal membrane transmitted along an axon. The axon is part of a nerve cell that conducts impulses.
When at rest the axon membrane has an electrical charge of?
When at rest, the axon membrane has a negative electrical charge inside compared to outside. This is known as the resting membrane potential and is typically around -70 millivolts.
What are the gaps called where the axon membrane is exposed?
Nodes of Ranvier
The junction between a motor neurons axon and the muscle cell membrane is called a neuromuscular junction or a?
The junction between a motor neruon's axon and the muscle cell membrane is called a neuromuscular junction or a myoneuraljunction?
An action potential is a travelling change in the axon's membrane permeability resulting in a flow of?
ions
The junction between a motor neurons axon and the muscle cell membrane is called?
neuromuscular junction or myoneural junction
When neuron is sufficiently stimulated this process starts the movement of ions across the axon membrane?
Depolavization
In addition to the nucleus cytoplasm and cell membrane a single neuron possesses what?
Several dendrites and one axon
The tightly wound cell membrane around the axon forms the myelin sheath and as acts as what?
jesus save me
