  2. 2- Skeletal Connective Tissues A- Bone • Produces solid matrix of calcium phosphate and collagen fibers. • Each osteon(Haversian systems) has a central canal containing blood vessels and nerves. • Bone is harder than cartilage. • The functions of bone are support, movement, protection of internal organs, mineral storage (calcium, phosphate) and blood cell development.

  3. B- Cartilage • Support soft tissues (nose, ear, trachea and vertebral discs). • Sliding areas for joints, facilitate bone movements. • The mature (adult) cell in cartilage is a chondrocyte خلية غضروفية • Cells are found in Lacunae (gap) within the matrix. • Fibers may be elastic or non-elastic

  4. 3- Blood (Vascular Tissue) • The matrix is a liquid called plasma (55%): • 90% water • 10% proteins, hormones, vitamins, nutrients etc. • There are three types of blood cells (45%).

  5. Third: Muscular tissues Characterized by • Tissue with cells having muscle fibers specialized for contraction. • It has large numbers of myofibrils made of the contractile proteins actin and myosin

  6. Types of Muscular Tissues • There are three types of muscular tissues in the vertebrate body. 1- Skeletal Muscles العضلات الهيكلية • It attaches to bones by tendons • Responsible for voluntary movements • Also called striated muscles 2- Cardiac muscles العضلات القلبية • It is found in the wall of the heart. • Cardiac muscles are branched. • Intercalated disc 3- Smooth muscles العضلات الملساء • No striations. • It is found in the walls of the digestive system, urinary bladder, arteries, and other internal organs. • The shape of the cells are spindle-shaped الشكل المغزلي

  7. Fourth: Nervous tissues الأنسجةالعصبية • Nervous tissue is the main component of the nervous system. • The functional unit of nervous tissue is the neuron, or nerve cell. • It consists of three parts: a cell body, a single axon and dendrites. • Dendrites transmit nerve impulses from their tips toward the rest of the neuron. • Axons transmit impulses toward another neuron, muscles or glands.
