Cells specializing in one function called W are often grouped together at a definite place inthe body. An example of W that forms the framework that supports the body is called X. X also anchors muscles and supports the main organs of the body. X can be connected to each other by Y, another group of specialized cells. Y is very elastic and has considerable strength. Another group of cells Z connects muscles to X.
What are denoted by W, X, Y, and Z
Answers
Answer:
Structure of Connective Tissue
Connective tissue has three main components:
Ground substance
Fibers
Cells
Together the ground substance and fibers make up the extracellular matrix. The composition of these three elements vary tremendously from one organ to the other. This offers great diversity in the types of connective tissue.
This is a drawing of the structural elements of connective tissue. It depicts cells suspended in a ground substance or matrix, with elastic and collagen fibers running throughout the matrix. CT is classified into two subtypes: soft CT and specialized CT. The soft CT subtype—loose, dense, and elastic tissues—are found in parts of our skin, tendons and blood vessels. The special CT subtype includes cartilage, bone, adipose tissue, blood, and lymphatic tissue, and provides a structural framework for the body and connects body tissues.
Structural elements of connective tissue: Connective tissues consist of three parts: cells suspended in a ground substance or matrix; and most have fibers running through it.
Ground substance is a clear, colorless, viscous fluid that fills the space between the cells and fibers. It is composed of proteoglycans and cell adhesion proteins that allow the connective tissue to act as glue for the cells to attach to the matrix. The ground substance functions as a molecular sieve for substances to travel between blood capillaries and cells.
