Interneurons
The brain is composed of two types of cells, neurons and glial cells.
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.
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.
Protons and neurons are in nucleus. electrons orbit around them
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.
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.
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 space between two neurons is a synapse.
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.
Neurons meet at the synapse.
The main cell type found in nervous tissue is the neuron. Neurons are responsible for transmitting electrical signals within the nervous system and are specialized for communication through both electrical and chemical signals.
Sensory neurons are typically unipolar in structure. This means they have a single process, or neurite, that extends from the cell body and splits into two branches, one leading to the peripheral nervous system and one leading to the central nervous system.
