Nerve tissue 1. Nerve tissue is composed of 2 main types of cells: Neurons-nerve cells that are specialized to detect and react to stimuli, by generating and conducting nerve impulses. Neuroglial cells- accessory cells for filling spaces and supporting neurons Retina - sensory tissue that lines the back of the eye. It contains millions of photoreceptors (rods for black & white and cones for color ) that convert light rays into electrical impulses that are relayed to the brain via the optic nerve Optic nerve - the nerve that transmits electrical impulses from the retina to the brai All nervous tissue, from the brain to the spinal cord to the furthest nerve branch, includes cells called neurons.

Brain, Spinal Cord, and nerves are composed of nervous tissue, they are specialized for being stimulated to transmit. Nervous Tissue Definition. Nervous tissue is the term for groups of organized cells in the nervous system, which is the organ system that controls the body's movements, sends and carries signals to and from the different parts of the body, and has a role in controlling bodily functions such as digestion. Nervous tissue is grouped into two main categories: neurons and neuroglia

Nervous tissue is the primary tissue that composes the central nervous system and the peripheral nervous system. Neurons are the basic unit of nervous tissue. They are responsible for sensing stimuli and transmitting signals to and from different parts of an organism Nervous - integration and control All specific tissues fall into one of the four basic types. In this section we look at epithelial and connective tissues. We will look at nerve and muscle tissues when we cover those topics Connective tissue in organs contains much less collagen and is more cellular. Organs, such as the small intestine, are structurally weaker than tendon because they require connective tissue to provide metabolic and immune support so the connective tissue must contain blood vessels, macrophages, lymphocytes tissues, as well as peripheral nerve and the sympa-thetic chain, concentrated melatonin 3- to 5-fold.

Nervous tissue, present in both the CNS and PNS, contains two basic types of cells: neurons and glial cells. A glial cell is one of a variety of cells that provide a framework of tissue that supports the neurons and their activities. The neuron is the more functionally important of the two, in terms of the communicative function of the nervous system There are more than 200 different types of tissues of the human body and all of these may be categorized into one of four groups: Epithelial tissue, Connective Tissue, Muscle tissue and Nervous tissue.
