What is the Electrical synapse between adjacent myocardial cells are called?
Gap junction
What are gap junctions in cells?
They are connections between animal cells which connects the cytoplasm between the cells; in neurons, they are electrical synapses.
What is synapses?
A synapse is a small gap at the end of a neuron that allows information to pass from one neuron to the next.
Are gap junctions chemical synapses?
Gap junctions are connections between cells and some do pass ions from one cell to another cell. Some are chemical, some are electrical synapses ans some are direct connections.
How the nerves transmit signals to the brain?
Nerves use electrical impulses to transmit signals to the brain. The gaps between the nerve endings are called synapses.
How many synapses does the brain have?
The brain is estimated to have around 100 trillion synapses. These synapses are the connections between neurons that allow them to communicate with each other.
Are there synapses in peripheral nervous system?
There are synapses between each and every neuron in the entire nervous system; so yes, there are synapses in the peripheral section of the nervous system.
What attaches cardiac muscle fibers together?
The myocardial cells are connected through tight junctions and gap junctions between the cell membranes of adjacent cells. The myocardium as a whole is covered by the pericardium on the outside and the endocardium on the inside.
How do synapses affect the delay between stimulus and response?
,
What are the communicating sites between to neurons called?
synapses
Describe the general structure of a synapse?
Synapses occur between two neurons. Electrical activitiy in the pre-synaptic neuron influences the post-synaptic neuron. There are two types of synapses in the body: Electrical and chemical. Electrical synapses occur in pre and post synaptic neurons that are joined via gap junctions. Currents from action potentials flow across the junction through channels called connexons. This current will depolarize the membrane of the post synaptic neuron to threshold, which will continue the action potential in the cell. Electrical synapses are fast and bidirectional. However, they are mainly found in cardiac and smooth muscles, and not in the mammalian nervous system.Chemical synapses use neurotransmitters. Depolarization occurs in the pre-synaptic neuron and calcium ions rush in. The calcium ions activate neurotransmitter release into the synaptic cleft. The neurotransmitters reach the post-synaptic neuron and cause action potentials to develop.Note: this can go into much more detail
What are neural signals?
Neural Signals are the electrical potential carrying the information to be transmitted between neurons/dendrites. They also initiate chemical stimulation on the synapses to transfer/carry forward the message from/to brain.
