Nervous tissue Structure [edit]. Nervous tissue is composed of neurons, also called nerve cells, and neuroglial cells. Typically, nervous tissue is categorized into four types of tissue. In the central nervous system (CNS), the tissue types found are grey matter and white matter.In the peripheral nervous system (PNS), the tissue types are nerves and ganglia. The tissue is categorized by its neuronal and neuroglial components.ypically, nervous tissue is categorized into four types of tissue.

Schwann cell In the peripheral nervous system, Schwann cells (named after German physiologist Theodor Schwann) wrap around axons of motor and sensory neurons to form the myelin sheath. Myelinating Schwann cells begin to form the myelin sheath in mammals during fetal development and work by spiraling around the axon, sometimes with as many as 100 revolutions. A well-developed Schwann cell is shaped like a rolled-up sheet of paper, with layers of myelin in between each coil.

- In your nervous system, cells called Schwann cells grow exceedingly large cell membranes, which wrap tightly around the long processes of nerves. Cell membranes of Schwann cells are unique in that they contain as much as 50 percent more cholesterol and up to 75 percent less protein than other types of cell membranes.This wrapping forms a thick insulating layer of cholesterol-based cell membrane known as myelin.yelin may also contain a small percentage of saturated fatty acids, which decrease the fluidity of the myelin membrane compared to cholesterol, which provides considerable membrane fluidity, according to Patricia Armati, PhD., editor of the book The Biology of Oligodendrocytes..

- Nerve cells are very variable in appearance, but all neurons have a cell body, also called soma or perikarion, and processes. The cell body contains the nucleus and organelles that maintain the nerve cell.The processes extend from the nerve cell to communicate with other cells.ervous tissue consists of nerve cells and associated supporting cells. All cells exhibit electrical properties, but nerve cells, also called neurons, are specifically designed to transmit electrical impulses from one site in the body to another, and to receive and process information.

Sensation & Perception Lesson Summary. Nervous tissue is composed of three main parts: nerves, the spinal cord and the brain. The primary function of nervous tissue is to receive stimuli and send the impulse to the spinal cord and brain. The brain sends back a response to the muscles via the nerves.

Nervous System The majority of the nervous system is tissue made up of two classes of cells: neurons and neuroglia. 1  Neurons. 2  There are 3 basic classes of neurons: afferent neurons, efferent neurons, and interneurons. 3  Afferent neurons. 4  Efferent neurons. 5  Interneurons. 6  Neuroglia.erves. Nerves are bundles of axons in the peripheral nervous system (PNS) that act as information highways to carry signals between the brain and spinal cord and the rest of the body. Each axon is wrapped in a connective tissue sheath called the endoneurium.

NERVOUS TISSUE Glial Cells. Regular connective tissue types surround the components of the central nervous system, but they are not found within the tissue. The glial cells, derived from neuroectoderm, serve roles of connective tissue within the CNS tissue.ERVOUS TISSUE. Nervous tissue is the fourth basic tissue type of the body and is organized into two basic systems: (1) the Central Nervous System (CNS) and (2) the Peripheral Nervous System (PNS).

Muscle tissue Muscle tissue is a soft tissue that composes muscles in animal bodies, and gives rise to muscles' ability to contract. This is opposed to other components or tissues in muscle such as tendons or perimysium. It is formed during embryonic development through a process known as myogenesis. Muscle tissue varies with function and location in the body. In mammals the three types are: skeletal or striated muscle; smooth or non-striated muscle; and cardiac muscle, which is sometimes known as semi-striated. Smooth and cardiac muscle contracts involuntarily, without conscious intervention.

- Schwann cells are the cellular counterparts to oligodendrocytes in the peripheral nervous system. Similarly to oligodendrocytes they form the myelin sheath. In contrast to the oligodendrocyte each Schwann cell is associated with only one axonal segment. While the myelin structure formed by oligodendrocytes and Schwann cells has a similar ultrastructure, it is not composed of an identical set of proteins.

Connective tissue Connective tissue (CT) is one of the four types of biological tissue that supports, connects or separates different types of tissues and organs in the body. It develops from the mesoderm. The other three types are epithelial, muscle, and nervous tissue. Connective tissue is found in between other tissues everywhere in the body, including the nervous system. In the central nervous system, the three outer membranes (the meninges) that envelop the brain and spinal cord are composed of connective tissue.

- 2. peripheral nervous system (PNS) - nerves extending toward or away from CNS and ganglia (aggregations of nerve cell bodies outside CNS). Nervous tissue consists of two major types of cells, 1. neurons-responsible for conduction, propagation, and reception of nervous impulses. Processes called axons or dendrites extend from these cells. 2. glial cells - (neuroglia) cells associated with neurons. No axons or dendrites. These cells are involved in nutrition, support, insulation, protection of neurons. If brain or spinal cord are sectioned, we find that two major areas of brain tissue may be defined on the basis of their color in fixed, unstained tissue.

Nerve Neurons are sometimes called nerve cells, though this term is potentially misleading since many neurons do not form nerves, and nerves also include non-neuronal Schwann cells that coat the axons in myelin.Each nerve is a cordlike structure that contains many axons.Within a nerve, each axon is surrounded by a layer of connective tissue called the endoneurium. The axons are bundled together into groups called fascicles, and each fascicle is wrapped in a layer of connective tissue called the perineurium.his article is about neural pathways of the peripheral nervous system. For other uses, see Nerve (disambiguation) . A nerve is an enclosed, cable-like bundle of axons (nerve fibers, the long and slender projections of neurons) in the peripheral nervous system.

Nervous tissue It is composed of neurons, or nerve cells, which receive and transmit impulses, and neuroglia, also known as glial cells or more commonly as just glia (from the Greek, meaning glue), which assist the propagation of the nerve impulse as well as providing nutrients to the neuron.ells of nervous tissue. Nervous tissue is the main component of the two parts of the nervous system; the brain and spinal cord of the central nervous system (CNS), and the branching peripheral nerves of the peripheral nervous system (PNS), which regulates and controls bodily functions and activity.

- Cell Types. There are four tissue types in the human body: epithelial, connective, nervous, and muscle tissues. Each tissue type is derived during embryonic development from the primary germ layer, which itself is composed of three layers known as the ectoderm, mesoderm, and endoderm.

Nervous Tissue Microglia are the cells in the CNS that can do this in normal, healthy tissue, and they are therefore also referred to as CNS-resident macrophages. The ependymal cell is a glial cell that filters blood to make cerebrospinal fluid (CSF), the fluid that circulates through the CNS. Because of the privileged blood supply inherent in the BBB, the extracellular space in nervous tissue does not easily exchange components with the blood.
