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 composed of two types of cells, neurons and glial cells. Neurons are the primary type of cell that most anyone associates with the nervous system. They are responsible for the computation and communication that the nervous system provides. They are electrically active and release chemical signals to target cells Nervous Tissue: Support Cells Support cells in the Central Nervous System (CNS) are grouped together as neuroglia Neuroglia literally means nerve glue The function of neuroglia is to support, insulate, and protect the delicate neurons of the brain Types of Neuroglia in CNS Astrocytes Star-shaped cells Half of all brain tissue Brace.

The term tissue is used to describe a group of cells that are similar in structure and perform a specific function. Histology is the the field of study that involves the microscopic examination of tissue appearance, organization, and function. Tissues are organized into four broad categories based on structural and functional similarities. These categories are epithelial, connective, muscle. Nervous Tissue. Nervous tissue is composed of two types of cells, neurons and glial cells. Neurons are the primary type of cell that most anyone associates with the nervous system. They are responsible for the computation and communication that the nervous system provides. They are electrically active and release chemical signals to target cells Of course, there are some places where there are breaks in the dense regular connective tissue of the tendon containing loose connective tissue associated with nerves and blood vessels or the occasional bit of adipose tissue. 2.

The human nervous system has two parts: the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system, which is composed of nerves and nerve networks throughout the body. The endocrine system is also essential to communication. The system utilizes glands located throughout the body that secrete hormones The PNS consists of all nervous tissue outside of the brain and spinal cord. It includes the ganglia, nerves, and receptors, as they are found in various parts of the body. Here ganglia and nerves will be the focus of discussion. Receptors will be discussed further in the sensory system module Disorders of the nervous system may involve the following: Vascular disorders, such as stroke, transient ischemic attack (TIA), subarachnoid hemorrhage, subdural hemorrhage and hematoma, and extradural hemorrhage.

Connective tissue is the tissue that connects, separates and supports all other types of tissues in the body. Like all tissue types, it consists of cells surrounded by a compartment of fluid called the extracellular matrix (ECM). However connective tissue differs from other types in that its cells are loosely, rather than tightly, packed within the ECM A basic knowledge of the general characteristics and cellular composition of these tissues is essential in histology, which is the study of tissues at the microscopic level. Tissues are groups of similar cells performing a common function. There are four categories of tissues: Epithelial tissue. Connective tissue. Nervous tissue. Muscle tissue The sciatic nerves, located in the legs, are the largest nerves in the body. 1  Each sciatic nerve stimulates movement of leg muscles and carries sensory messages from the leg to the spine. The right and left sciatic nerves each control functions on the ipsilateral (same) side of the body. gilaxia / Getty Images

A nerve is an organ composed of multiple nerve fibers bound together by sheaths of connective tissue. The sheath adjacent to the neurilemma is the endoneurium, which houses blood capillaries that feed nutrients and oxygen to the nerve. In large nerves, fibers are bundled into fascicles and wrapped in a fibrous perineurium As the name implies, connective tissue serves a connecting function: It supports and binds other tissues in the body. Unlike epithelial tissue, which has cells that are closely packed together, connective tissue typically has cells scattered throughout an extracellular matrix of fibrous proteins and glycoproteins attached to a basement membrane. The primary elements of connective tissue.
