Essay on Muscle Contraction - English Essays for Children.

A tissue is an ensemble of cells, not necessarily identical, but from the same origin, that together carry out a specific function. There are four types of tissue these include, epithelial tissue, muscle tissue, connective tissue and nerve tissue. Epithelial tissue covers the whole surface.

Muscle and nervous tissues are sometimes called composite tissues because they contain small amounts of areolar tissue along with their own muscle or nerve cells. Muscle and nervous tissues are both richly vascularized. There are three types of muscle tissue: skeletal, cardiac and smooth.

Nervous tissue makes up the different parts of our nervous system. It allows us to receive stimuli and process the information. Learn more about this tissue and take a short quiz at the end.

Muscle is one of the four fundamental types of tissue present in animals. It is a soft tissue primarily responsible to produce movement of a body part. Its cells convert the chemical energy of ATP into the mechanical energy of motion and exert a useful pull on another tissue. More specifically, muscle contraction serves the following.

Start studying Muscle and Nerve Tissue. Learn vocabulary, terms, and more with flashcards, games, and other study tools.

Nervous tissue is composed of neurones and neuroglia (supporting cells closely related to the neurones) associated with vessels and connective tissue. This tissue is subdivided into two major compartments: the central nervous system and the peripheral nervous system. The central nervous system is composed of (a) the brain (cerebrum, cerebellum.

It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning. To do all these things, cells in nervous tissue need to be able to communicate with each other by way of electrical nerve impulses. The cells in nervous tissue that generate and conduct impulses are called neurons or.

The objective of this lab was to extract proteins from unknown samples of fish muscle tissue and then qualitatively analyze this protein mixture by performing sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) twice. The protein bands of the first gel-representing the total amount of proteins found in the tissue homogenate.

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.

Muscle Tissue Summary Muscle Tissue Appearance Nucleus Control Skeletal Striated Multi Voluntary Cardiac Striated Single Involuntary Smooth Not striated Single Involuntary. Nervous Tissue ! Located in brain, spinal cord, and nerves ! Cells are called neurons ! Neurons send and received impulses from one part of the body to another. Nervous Tissue ! Cell body- large center of cell where.

Muscle fibres can contract and therefore have good extensibility. Most of the restriction in the flexibility of a muscle derives from the connective tissue that surrounds the muscle and the muscle fibres. Rigorous massage movements, such as kneading and wringing, stretch and loosen the skin and underlying tissue. Increased localised blood.

In summary, the three types of muscle tissue are skeletal, cardiac, and smooth. Cardiac and skeletal are both striated muscle as repeating units called sarcomeres give the cells a striated.
