What are the cells of the brain?
The brain is composed of two types of cells, neurons and glial cells.
What are the only two types of cells that have excitable membranes?
The only two types of cells that have excitable membranes are neurons and muscle cells. Neurons transmit electrical signals in the nervous system, while muscle cells generate electrical signals that lead to muscle contraction.
What type of neurons make up the central nervous system?
The central nervous system is made up of two main types of neurons: sensory neurons, which transmit information from the body to the brain, and motor neurons, which transmit information from the brain to the body.
What are the three types of neurons based on the organization of their processes?
The three types of neurons based on the organization of their processes are unipolar, bipolar, and multipolar neurons. Unipolar neurons have a single process that extends from the cell body, typically functioning as sensory neurons. Bipolar neurons possess two processes, one axon and one dendrite, and are often found in sensory systems like the retina. Multipolar neurons, the most common type, have multiple dendrites and one axon, primarily serving as motor neurons and interneurons in the central nervous system.
WHERE ARE THE TWO TYPES OF SUBATOMIC PARTICLES LOCATED IN SILICON?
Protons and neurons are in nucleus. electrons orbit around them
What are the two types of nervous tissue?
neurons (brain cells) & neuroglia (support)---------------------------------------------------Multipolar Neurons (3+ processes) They are the most common neuron type in humans (more than 99% of neurons belong to this class) and the major neuron type in the CNS Bipolar Neurons Bipolar neurons are spindle-shaped, with a dendrite at one end and an axon at the other . An example can be found in the light-sensitive retina of the eye. Unipolar Neurons Sensory neurons have only a single process or fibre which divides close to the cell body into two main branches (axon and dendrite). Because of their structure they are often referred to as unipolar neurons.
What are two major types of cells that form nervous tissue?
First is the neuroglia, function is to support and protect the cells of the nervous system. Second is neurons, which are responsible for conducting nerve impulses from one part of the body to another.
What are neurons with two processes classified as?
Neurons with two processes are classified as bipolar neurons. These neurons have one dendrite and one axon extending from their cell body. Bipolar neurons are commonly found in specialized sensory pathways like the visual and olfactory systems.
The effector pathway of the autonomic nervous system generally contain which neurons?
The effector pathway of the autonomic nervous system typically contains two types of neurons: preganglionic neurons and postganglionic neurons. The preganglionic neurons originate in the central nervous system and synapse with postganglionic neurons located in autonomic ganglia. These postganglionic neurons then project to various target organs, mediating involuntary functions such as heart rate, digestion, and respiratory rate.
What type of neuron is also called an interneurn because it carries messages between the other two types of neurons Associative Afferent Efferent?
The type of neuron that is also known as an interneuron is the associative neuron. Interneurons are responsible for transmitting signals between sensory neurons (afferent neurons) and motor neurons (efferent neurons) in the central nervous system.
What is the point called where two neurons meet?
The space between two neurons is a synapse.
What are the two types of nerve cell and what are their functions?
The two main types of nerve cells are neurons and glial cells. Neurons are responsible for transmitting signals throughout the nervous system, processing information, and communicating between different parts of the body. Glial cells, on the other hand, provide support, protection, and nourishment for neurons, as well as maintaining homeostasis and forming myelin, which insulates nerve fibers to enhance signal transmission.
