Nervous System Schwann cells: these cells provide the myelin that covers neurons in the peripheral nervous system. Larger neurons are covered in a myelin sheath. Myelin is high in lipid and serves the same purpose as insulation around electrical wires.Myelinated axons conduct nerve impulses faster.hese cells form the substance of the brain, spinal cord, and peripheral nervous system. The brain is composed of the basic units of the cerebral hemispheres, brainstem, and cerebellum. The cerebral hemispheres can be further categorized by structure and function.

- 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.

THE NERVOUS SYSTEM The Central Nervous System (CNS) is composed of the brain and spinal cord. The CNS is surrounded by bone-skull and vertebrae. Fluid and tissue also insulate the brain and spinal cord. Areas of the brain.he Peripheral Nervous System (PNS) connects the CNS to other parts of the body, and is composed of nerves (bundles of neurons). Not all animals have highly specialized nervous systems. Those with simple systems tend to be either small and very mobile or large and immobile.

Connective tissue Connective tissue (CT) is one of the four types of biological tissue that support, connect, or separate different types of tissues and organs in the body. 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 outer membranes, the meninges, that cover the brain and spinal cord are composed of connective tissue.ther kinds of connective tissues include fibrous, elastic, and lymphoid connective tissues. Fibroblasts are the cells responsible for the production of some CT. Type-I collagen, is present in many forms of connective tissue, and makes up about 25% of the total protein content of the mammalian body.

Structure and Functions of Nervous Tissue 1 : : Forms part of the Myelin sheath (protective covering) around a PNS neuron. 2  That is, Schwann cells wrap around the axon of the neurone, forming areas in which myelin forms-resulting in the formation of a myelin sheath around the axon-between the axon and the Schwann cell(s).ligodendrocyte cells are found in the Central Nervous System (CNS), that is in the tissues of the Brain and Spinal Cord. : Oligodendrocytes differ from astrocytes (listed higher-up this page) by having fewer and thinner processes and no gap junctions. : 1  Forms supporting network around CNS neurons.

THE SPINAL CORD, CRANIAL NERVES AND SPINAL NERVES Meninges. Three layers of membranes known as meninges protect the brain and spinal cord. The delicate inner layer is the pia mater. The middle layer is the arachnoid, a web-like structure filled with fluid that cushions the brain. The tough outer layer is called the dura mater.

Definitions &Translations In the central nervous system, the analogous structures are known as tracts. 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.ithin 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.
