fibers inside of the cells causes these light and dark bands. Striations indicate that a muscle cell is very strong‚ unlike visceral muscles. The cells of cardiac muscle are branched X or Y shaped cells tightly connected together by special junctions called intercalated disks. Intercalated disks are made up of fingerlike projections from two neighboring cells that interlock and provide a strong bond between the cells. The branched structure and intercalated disks allow the muscle cells to resist

Comparison between Tradition and Modern Treatments for Chronic Ankle Instability Introduction Ankle sprains are one of the most commonly encountered musculoskeletal injuries in both athletes and sedentary people. The majority of sprains are caused by an inversion mechanism of the plantarflexed foot. As a result‚ the lateral ankle ligaments are most frequently injured‚ with injury to the anterior talofibular ligament (ATFL) the most common. Injuries to the

HISTOLOGY: EPITHELIAL TISSUE o Human body composed of 4 basic types of tissue: epithelial‚ connective‚ nervous and muscular o Formed by cells and molecules of the extracellular matrix o Connective tissue: characterized by the abundance of extracellular fluid o Organs can be divided by parenchyma (composed of cells for main function of organ) and stroma ( supporting tissue) o Except in brain and spinal cord stroma made of connective tissue o Epithelial tissue: covering‚ lining protecting surfaces
