Tissue types within the human body
Function of the nervous tissue include acting as a sensory input, incorporation, organisation of muscles and glands, homoeostasis and mental activity. All living cells have the capability of react to stimuli. The nervous tissue specialised to react to stimuli and conducts impulses to various organs in the body which bring about a response to the stimulus. The basic structure of the nervous tissue is a neuron, consisting of a nervous cell body and serval processes dendrites, which carrys impulses towards the nervous cell body and axon which carry impulses away from the cell body. Nervous tissues are found is all organs in the body some have more than others thought, Maximum in the nervous system, least in fatty deposits. Some examples are brain which is a main nervous tissue but also an organ also the heart that is one of our most important organ but also a nervous tissue.
Here’s a labelled picture of a nervous tissue;
The function of the epithetical tissue include transportation of materials, protection of underlying tissues, absorption of water and nutrients and secretions of waste products. Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialised to form the covering or lining of all internal and external body surfaces. Epithelial tissue that occurs on surfaces on the interior of the body is known as endothelium. Epithelial cells are packed tightly together, with almost no intercellular spaces and only a small amount of intercellular substance. Epithelial tissue, regardless of the type, is usually separated from the underlying tissue by a thin sheet of connective tissue; basement membrane. The basement membrane provides...
