Dense regular connective tissue. Densely spaced, parallel collagen fibers and fibroblasts. Binds bones together and attaches muscle to bone. Collagen also strengthens bone and cartilage.
Dense regular connective tissue
Connective tissue (CT) is a kind of biological tissue that supports, connects, or separates different types of tissues and organs of the body. It is one of the four general classes of biological tissues—the others of which are epithelial, muscular, and nervous tissues.
All CT has three main components: cells, fibers, and extracellular matrices, all immersed in the body fluids.
Connective tissue in skeletal muscle
Dense regular connective tissue provides connection between different tissues. The collagen fibers in dense regular connective tissue are bundled in a parallel fashion.
Dense regular connective tissue has great tensile strength that resists pulling forces especially well in one direction.
Dense connective tissue
Each skeletal muscle consists of two kinds of tissue: connective tissue, and muscle tissue. Connective tissue of skeletal muscle contains:
The layers of connective tissue have a major role in protection and covering of muscle fibers, muscle fascicles, and an entire skeletal muscle. Tendons attach the skeletal muscles to bones. Aponeurosis is structurally as tendon that connects the muscles together, or to bone.

Dense connective tissue, also called dense fibrous tissue, has fibers as its main matrix element.
Dense connective tissue is mainly composed of collagen type I. Crowded between the collagen fibers are rows of fibroblasts, fiber-forming cells, that manufacture the fibers. Dense connective tissue forms strong, rope-like structures such as tendons and ligaments. Tendons attach skeletal muscles to bones; ligaments connect bones to bones at joints. Ligaments are more stretchy and contain more elastic fibers than tendons. Dense connective tissue also make up the lower layers of the skin (dermis), where it is arranged in sheets.
Science of drugs including their origin, composition, pharmacokinetics,

Pharmacology (from Greek φάρμακον, pharmakon, "poison" in classic Greek; "drug" in modern Greek; and -λογία, -logia "study of", "knowledge of") is the branch of medicine and biology concerned with the study of drug action, where a drug can be broadly defined as any man-made, natural, or endogenous (within the body) molecule which exerts a biochemical and/or physiological effect on the cell, tissue, organ, or organism. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals.
