What is tissue definition?
Tissue is a group of cells that have similar structure and that function together as a unit. A nonliving material, called the intercellular matrix, fills the spaces between the cells.
Which is the best definition of tissue?
Tissues are groups of cells that have a similar structure and act together to perform a specific function. The word tissue comes from a form of an old French verb meaning “to weave”. Groups of tissues make up organs in the body such as the brain and heart.
What is a tissue in biology simple definition?
Biology. an aggregate of similar cells and cell products forming a definite kind of structural material with a specific function, in a multicellular organism. tissue paper.
What is the definition of tissue in biology quizlet?
tissue. a group of biological cells that perform a similar function.
What is an organism quizlet?
Organisms. a living thing that is made of one or more cells, uses energy, moves, responds to its environment, reproduces, adapts, and has a life span. Cell.
What is nervous tissue quizlet?
Nervous tissue. – Is found in the brain, spinal cord, and nerves and is characterized by the ability to conduct electrical signals called action potentials. – Nervous tissue consists of neurons, which are responsible for its conductive ability, and support cells called neuroglia. Neurons.
What is nerve tissue characterized by?
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 1).
What are the 4 main tissues?
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).
Which cells are part of nervous tissue quizlet?
There are two main cell types: neurons and neuroglia. The nerve cell known as the “functional unit”. Transmits the impulses of the nervous system.
What are the two main cell types found in nervous tissue?
Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the “conducting” cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell.
What are cells in the nervous system called?
Neurons are the information-processing cells of the nervous system. They are categorized as receptors, interneurons, or effectors, depending on their function. The dendrites of a neuron provide an extended receptive surface for the cell, increasing greatly the number of synaptic inputs.
What are the 2 major types of cells that form nervous tissue?
The nervous system consists of nervous tissue, which is composed of two principal types of cells called neuron and neuroglia.
What are the different types of nervous tissue?
Nervous tissue is grouped into two main categories: neurons and neuroglia. Neurons, or nerves, transmit electrical impulses, while neuroglia do not; neuroglia have many other functions including supporting and protecting neurons.
