What are nerve cells specialized to receive and conduct electrical impulses?
Nerve cells, or neurons, are specialized to receive and transmit electrical impulses throughout the body. They have structures called dendrites that receive signals from other neurons, and an axon that transmits signals to other cells. Neurons have a membrane potential that allows them to generate and transmit electrical impulses known as action potentials.
There are two primary kinds of cells in the heart muscle These cells are the myocardial and electrical cells?
Myocardial cells lines the muscular walls of heart tissues (contractility and extensibility) Electrical cells is the conduction system of the heart. Can be conducted 3 ways: automaticity that generates action potential, excitability that responds to electrical impulses and conductivity transmit an electrical impulses from one cell to the next
What kinds of specialized cells make up the heart?
The main specialized cells that make up the heart are cardiomyocytes responsible for contraction, pacemaker cells that generate electrical impulses, and conductive cells that help spread the electrical signals throughout the heart.
What is the neuron that carries impulses to the nervous cell body is called what?
The neuron that carries impulses towards the cell body is called a dendrite. Dendrites receive signals from other neurons and transmit them towards the cell body for processing. This input helps the neuron determine whether or not to generate an action potential.
What Cells that set the pace for the beating of the heart as a whole are also called?
Pacemaker cells, also known as the sinoatrial (SA) node, are specialized cells in the heart that generate electrical impulses to regulate its rhythm. These cells initiate each heartbeat and set the pace for the entire heart.
What are neurons that change light into electrical impulses called?
Neurons that convert light into electrical impulses are called photoreceptor cells. These specialized cells are found in the retina of the eye and are responsible for detecting light and converting it into signals that the brain can interpret as visual information.
What are nerve cells specialized to receive and conduct electrical impulses?
Nerve cells, or neurons, are specialized to receive and transmit electrical impulses throughout the body. They have structures called dendrites that receive signals from other neurons, and an axon that transmits signals to other cells. Neurons have a membrane potential that allows them to generate and transmit electrical impulses known as action potentials.
Do nerve cells carry electrical impulses?
Of course they do. They are modified for that
What is the function of the Vestibulospinal?
to convey impulses of equilibrium to anterior horn cells of spinal cord

What group of fibers spreads impulses at up to 2 meters per second?
The group of fibres that spread impulses throughout the body are called nerves or neurons. They are a specific type of cells which can undergo electrical stimulation to conduct impulses.
What contains receptor that convert sound vibrations to impulses sent to the brain?
The cochlea in the inner ear contains receptors called hair cells that convert sound vibrations into electrical impulses. These impulses are then sent to the brain via the auditory nerve, where they are interpreted as sound.
What cells stimulate both atria to contract?
The sinoatrial (SA) node, located in the right atrium, is responsible for initiating the electrical impulses that stimulate both atria to contract simultaneously. These electrical impulses spread through specialized conducting fibers called the internodal pathways to ensure coordinated atrial contraction.
Type of tissue that sends electrical signals through the body?
Nerve cells can transmit electrical impulses throughout the body.
What is the fatty materiel that covers the axon and helps with nerve impulses?
It is called as myelin sheath. It acts as an insulator of the electrical wire. It is made up of cells.
What cells transmit and receive impulses?
nervous tissue.
Why can a nerve still be alive when a person is dead?
A nerve is simply a line of cells through which electrical impulses travel. These electrical impulses are generated by the movement of Sodium and potassium ions into and out of the cells which generates an action potential (impulse). Nerve cells can be stimulated once a person is dead if an electrical impulse is generated and so appear to be alive.
