What is tissue category?
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 is tissue and its classification?
A tissue is a group of cells, in close proximity, organized to perform one or more specific functions. There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
What are the subtypes of tissues?
Overview of the four basic tissue types , connective tissue, nervous tissue, and muscle tissue.
What kind of tissue is nervous tissue?
The other type of cell is neuroglia, or glial, cell. The word “neuroglia” means “nerve glue.” These cells are nonconductive and provide a support system for the neurons. They are a special type of “connective tissue” for the nervous system.
How do nervous tissue and muscle tissue work together?
The function of muscle tissue (smooth, skeletal, and cardiac) is to contract, while nervous tissue is responsible for communication.
Which type of tissue would be found in the epidermis?
The epidermis is composed of keratinized, stratified squamous epithelium. It is made of four or five layers of epithelial cells, depending on its location in the body. It does not have any blood vessels within it (i.e., it is avascular).
What are the general characteristics of nervous tissue?
Nervous tissue is characterized as being excitable and capable of sending and receiving electrochemical signals that provide the body with information. Two main classes of cells make up nervous tissue: the neuron and neuroglia (Figure 4.5. 1 The Neuron).
What are the two unique characteristics of nervous tissue?
Integration and communication are the two major functions of nervous tissue. Nervous tissue contains two categories of cells — neurons and neuroglia.
What are the 4 types of neurons?
Neurons are divided into four major types: unipolar, bipolar, multipolar, and pseudounipolar.
What is the most common type of neuron?
Interneurons. Interneurons are neural intermediaries found in your brain and spinal cord. They’re the most common type of neuron. They pass signals from sensory neurons and other interneurons to motor neurons and other interneurons.
