What structure is formed when a neuron synapses with many muscle cells?

neuromuscular junction, also called myoneural junction, site of chemical communication between a nerve fibre and a muscle cell. The neuromuscular junction is analogous to the synapse between two neurons.

What is the structure of the synapse?

The synapse consists of three elements: 1) the presynaptic membrane which is formed by the terminal button of an axon, 2) the postsynaptic membrane which is composed of a segment of dendrite or cell body, and 3) the space between these two structures which is called the synaptic cleft.

What 3 structures make up the synapse?

Synapses are composed of three main parts: The presynaptic ending that contains neurotransmitters. The synaptic cleft between the two nerve cells. The postsynaptic ending that contains receptor sites.

What is the structure of the neuromuscular junction?

The neuromuscular junction is a chemical synapse between the motor neuron and the skeletal muscle fiber. It consists of a presynaptic terminal, synaptic cleft, and a postsynaptic membrane or cell.

What happens at the synapse between two neurons?

At a synapse, one neuron sends a message to a target neuron—another cell. At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters. These molecules bind to receptors on the postsynaptic cell and make it more or less likely to fire an action potential.

What is a synapse in a neuron?

synapse, also called neuronal junction, the site of transmission of electric nerve impulses between two nerve cells (neurons) or between a neuron and a gland or muscle cell (effector). A synaptic connection between a neuron and a muscle cell is called a neuromuscular junction.

What is structure of a neuron?

The takeaway. Nervous system cells are called neurons. They have three distinct parts, including a cell body, axon, and dendrites. These parts help them to send and receive chemical and electrical signals.

What is the synapse of a neuron?

What happens in the synapse between two neurons?

What structures from a muscle cell and a neuron meet at the neuromuscular junction?

The structures that meet at the neuromuscular junction are (d) the synaptic terminus and the sarcolemma.
