Basis Tissue Types
Muscle, Epithelial, Connective
Term | Definition |
---|---|
Skeletal (Muscular tissue) | Causes movement of the skeleton |
Smooth (Muscular tissue) | Concerned with movement within organs and blood vessels |
Cardiac (Muscular tissue) | Concerned with beating of the heart. |
Simple - Squamous (Epithelial) | Cells are flat and plate-like. Found where absorption is required. |
Simple - Cuboidal (Epithelial) | Cells are cube-shaped with central spherical nucleus. Found in glands and ducts |
Simple - Columnar (Epithelial) | Tall and rectangular. The layers of cells may contain mucus-secreting goblet cells or may be ciliated, respiratory tract, lining the gut with a covering of microvilli, and in secretory glands of the digestive and endocrne systems. |
Compound - Stratified (Epithelial) | the first layers of cells are cuboidal, becoming flatter as they are moved towards the surface of the tissue by new cells forming beneath them. |
Compound - Transitional (Epithelial) | Modified, stratified, containing a combination of shpaes. Found where ability to stretch is required. |
Compound - Glandular (Epithelial) | Consisting of either individual goblet cells with a single unbranched duct or a mass of secretory cells with a branched duct system forming a gland. |
Compound - Glandular - Endocrine (Epithelial) | Surrounded by an extensive capillary network and are ductless, secreting hormones directly into the blood stream. |
Compound - Glandular -Exocrine (Epithelial) | simple or compound, have ducts and secrete on to an epithelial surface |
Areolar tissue (Connective Tissue) | Consists of a loose network of collagen fibres and surrounds organs providing support and flexibility. (Under skin) |
Dense Connective Tissue (Connective Tissue) | Large proportion of collagen fibres, which provide great strength, (Tendons and ligaments) |
Blood (Connective Tissue) | Transports essential nutrients, gases, waste products, hormones and enzymes to and from all body cells. Consist of many cell types. Suspended in a liquid matrix called plasma. |
Cartilage (Connective Tissue) | Mixture of collagen and elastic fibres provides shape, protection for organs and movement. Is a dense clear blue material that is tough and can be elastic or rigid. Found mainly in joints. Has no blood vessels but is covered by a membrane called perichond |
Cartilage - Hyaline (Connective Tissue) | Chondrocytes lie within a hyaline matrix with collagen fibres running through. |
Cartilage - Fibrocartilage (Connective Tissue) | Stronger than hyaline cartilage and the matrix contains fibrous collagen fibres. |
Cartilage - Elastic (Connective Tissue) | Has a hyaline matrix and many elastic fibres that gives it elastic properties. |
Bone (Connective Tissue) | Provides support and is a means of attachment for skeletal muscles. Consists of cells embedded in a comparatively hard matrix or ground substance. Cells are arranged as cylinders in layers known as Haversian systems (which give bone its strength) |
Bone - Osteoblast (Connective Tissue) | Responsible for the secretion of material which, when mineralised or calcified, will become bone. |
Bone - Oseocytes (Connective Tissue) | Osteoblasts become trapped in the forming bone |
Bone - Osteoclasts (Connective Tissue) | Responsible for reabsorbing materials and for the remodelling of bone. |
Long Bone - Compact (Connective Tissue) | Forming the dense walls of the bone shaft. |
Long Bone - Cancellous or spongy (Connective Tissue) | Forming the central medullary cavity and providing support for haemopoietic tissue. |
Nervous Tissue (Connective Tissue) | Conducts electrical or nerve impulses to and from the central nervous system by means of neurons. |
