The nervous system consists of nervous tissue, which is composed of two principal types of cells called neuron and neuroglia.
What are the two main types of nervous tissue quizlet?
There are two main cell types: neurons and neuroglia. The nerve cell known as the “functional unit”.
What are the types of tissue in the nervous system?
Structure. Nervous tissue is composed of neurons, also called nerve cells, and neuroglial cells. Four types of neuroglia found in the CNS are astrocytes, microglial cells, ependymal cells, and oligodendrocytes.
What are the three types of nervous tissue quizlet?
Types of Nervous Tissue
- dendrites (receive info from other neurons)
- cell body (contains nucleus, essential to life of cell)
- single axon (transmits info away from cell body)
What type of tissue are neurons quizlet?
– Nervous tissue consists of neurons, which are responsible for its conductive ability, and support cells called neuroglia.
What are types of tissue?
There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues). Epithelial tissue provides a covering (skin, the linings of the various passages inside the body).
What are the 3 types of nervous system?
It has three parts: The sympathetic nervous system. The parasympathetic nervous system. The enteric nervous system.
What is the junction between two nerve cells?
Synapse – The junction between the axon of one neuron and the dendrite of another, through which the two neurons communicate.
What are the 2 main functions of the nervous system?
The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses). The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).
What are the two main differences between the supporting cells and the neurons?
Nervous tissue contains two categories of cells — neurons and neuroglia. Neurons are highly specialized nerve cells that generate and conduct nerve impulses. Neuroglia are supporting cells that provide physical sport, remove debris, and provide electrical insulation.
What are three main functions of the nervous system give an example of each quizlet?
Terms in this set (3)
- sensory input. when sensory receptors monitor changes that occur both inside and outside of the body.
- integration. when sensory information is interpreted and the appropriate response is taken.
- motor output. response that is performed by effectors- muscles or glands.
What are the cells of nervous tissue called?
The cells in nervous tissue that generate and conduct impulses are called neurons or nerve cells. These cells have three principal parts: the dendrites, the cell body, and one axon.
Which is the most common type of neuron structure?
Multipolar neurons are the most common neuron in the vertebrate nervous system and their structure most closely matches that of the model neuron: a cell body from which emerges a single long axon as well as a crown of many shorter branching dendrites.
What is Neuroglial?
Listen to pronunciation. (noor-OH-glee-uh) Any of the cells that hold nerve cells in place and help them work the way they should. The types of neuroglia include oligodendrocytes, astrocytes, microglia, and ependymal cells.
