Witryna17 sty 2024 · A single axon routes the nerve impulse from the cell body to another neuron or an effector organ. The axon can have many terminal branches, so each time the nerve fires, it can stimulate more than one cell. Key Points Nervous tissue is composed of neurons and supporting cells called neuroglia, or ” glial cells.” There … Witryna5 paź 2024 · The cardiac conduction system is the electrical pathway of the heart that leads to atrial and ventricular contraction. The conduction system consists of pacemaker cells that generate spontaneous action potentials, and then deliver those impulses throughout the heart. The cardiac conduction system comprises the following …
WitrynaEpendymal cells are cells that line the fluid-filled spaces in the brain and spinal cord, and help to produce and circulate cerebrospinal fluid. The myelin sheath is a layer of fatty material that surrounds axons, produced by oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. It helps to insulate ... Witryna13 lis 2024 · The principal function of nerve cells is to generate the electric nerve impulses, process, transmit and receive them between various organs. They carry these nerve signals from one part of the body to another part of the body. In layperson’s terms, nerve cells receive impulses or signals (chemical ions) from other nerve cells via …

Witryna10 lip 2024 · Nerve impulses are received at neuronal dendrites, passed through the cell body, and are carried along the axon to the terminal branches. Since axons can have numerous branches, nerve impulses can be transmitted to numerous cells. These branches end at junctions called synapses.
