if you were to watch an individual neurotransmitter molecule just after it was released what would happen to it

6 0

Neurotransmitter leaves the presynaptic cell by exocytosis. It is released in the synaptic space, and moves to the postsynaptic membrane to meet its receptor. When binding occurs, it triggers a response in the new cell.

-----------------------------------------

Every neuron forms connections with another cell.

When a presynaptic cell sends information, a neurotransmitter is released.

After the exocytosis event, this chemical substance travels through the synaptic space forward to the other cell. Once there, it binds to its receptors in the postsynaptic membrane.

When the joining occurs, the receptor acquires a channel shape. This change allows the ion transference that will make possible the modification of the action potential.

This binding produces the excitatory postsynaptic potential -depolarization-.

A new action potential initiates in the postsynaptic cell and spreads to the rest of the membrane, depolarizing it.

If the communication between cells needs to stop, the neurotransmitter will be taken out from the synaptic space instead of binding to its receptor.

There are two mechanisms by which the neurotransmitter can be eliminated: by deactivation or reuptake.

how would the function of synovial joints be changed if they lacked joint cavities and the bones were united instead? Explain.

Anettt [7]

Answer:

In the absence of joint spaces (cavities) and bones fused together, body movements would be null or reduced.

Explanation:

The joints are the spaces where two bones meet, with cartilaginous tissue - articular cartilage and ligaments - to allow elasticity and body movements.

The articular cavities are spaces where bone union occurs through ligaments, surrounded by an articular capsule and upholstered inside by a membrane that produces liquid, the membrane and synovial fluid, respectively. These joints are usually found in the mobile body segments.

If the joint cavities did not exist, and the joints occurred between bone and bone, body mobility would not be possible. In the case of the skull bones, they do not have joint space, since their function is the protection of the organs of the central nervous system, not movement.

How does deforestation increase the warming of earth

maks197457 [2]

Answer:

Explanation:

Forests and trees store carbon . When they are degraded or completely cleared, e.g. by fire – a process referred to as deforestation – this stored carbon has the potential to be released back into the atmosphere as carbon dioxide and contribute to climate change .
