It is composed of two major types of cells: neurons and support cells (glia).

CONNECTIVE

connective tissue, group of tissues in the body that maintain the form of the body and its organs and provide cohesion and internal support.

Connective tissue is one of the four primary types of animal tissue, along with epithelial tissue, muscle tissue, and nervous tissue

[1] It develops from the mesenchyme derived from the mesoderm the middle embryonic germ layer

[2] Connective tissue is found in between other tissues everywhere in the body, including the nervous system.

All are immersed in the body water. The cells of connective tissue include fibroblasts, adipocytes, macrophages, mast cells and leucocytes.

Structure and its function

Collagen fibers are made up of closely packed thin collagen fibrils that run a wavy course in tissues

These parallel fibrils are bundles with flexible proteoglycans to offer an essential mechanical property

They offer flexible but powerful resistance to pulling force.

Specifically, in loose connective tissue, collagen runs in a parallel course and then joins to form a larger bundle.

They split from each other and join back together at varying locations creating a three-dimensional meshwork.

Dense connective tissue such as ligaments and tendons are compromised mainly of densely packed collagen fibers
