The neurotransmitter binds to any receptor that it fits. Neurons are cells within the nervous system that transmit information to other nerve cells, muscle, or gland cells. The endocrine system consists of a series of glands that produce chemical substances known as. The upper motor neurons, lower motor neurons, or both can be affected. Researchers say a drug used to treat epilepsy seizures shows promise in reducing autism-like behavior in mice. This site is using cookies under cookie policy . There are no weak action potentials they are all the same size; only their firing frequency changes. Chapter 1: Cytology of the central nervous system. Activated receptors would open or close ion channels, which would affect the membrane potential of the postsynaptic cell. Many axons are covered with a layered myelin sheath, which accelerates the transmission of electrical signals along the axon. The sensory receptor the dendrite receptor looks exactly the same as the terminal end which is not labeled. But researchers are still trying to figure out the best way to use these stem cells to produce specific types of neurons in the laboratory setting. A ________ scan involves taking a number of x-rays of a particular section of a persons body or brain. Neurons are cells within the nervous system that transmit information to other nerve cells, muscle, or gland cells. This illustration shows a prototypical neuron, which is being myelinated by a glial cell. Which of the following senses is associated with the temporal lobe? Current research is uncovering important new roles for glia in brain function. 3.2 Cells of the Nervous System - Introductory Psychology The dendrites are covered with synapses formed by the ends of axons from other neurons. Neurons are the central building blocks of the nervous system, 100 billion strong at birth. There can be more than one interneuron in a circuit. At the end of the terminal button is a gap known as a synapse. Interneurons are neural intermediaries found in your brain and spinal cord. 2. neuron: [noun] a grayish or reddish granular cell that is the fundamental functional unit of nervous tissue transmitting and receiving nerve impulses and having cytoplasmic processes which are highly differentiated frequently as multiple dendrites or usually as solitary axons which conduct impulses to and away from the cell body : nerve cell 1.
