! DID YOU KNOW? 1. How do cells of three types of Muscle tissues differ from one another automatically? Skeletal muscle cells are long multinucleate cells with obvious striations.
Deep Fascia connective tissue with dense irregular tissue that lines the body wall and limbs. Muscle Cell muscle fibers that are elongated and striated and multinucleated. A skeletal muscle fiber is actually embryonic cells that have fused together to form one large cell with multiple nuclei. Perimysium dense
Outcome 1 Understand anatomy and physiology in relation to moving & positioning individuals. 1.1 Bones and muscles are concerned with the movement of the body. The skeleton is a rigid framework that gives shape and support to the body and is jointed to permit movement. The vertebral column is the basis of the skeleton and consists of a series of bony rings united by inter-vertebral discs of cartilage. All bones give attachment to muscles, which are responsible for 50% of our body weight and also permit movement.
Compare and contrast Cardiac and Skeletal Muscle. Discuss how their differences enable them to carry out their function more effectively. Skeletal, cardiac and smooth muscle account for nearly half of our body weight, their roles essential for normal bodily function. Skeletal muscles; attached to the skeleton via tendons; maintain body posture, are voluntary controlled and have antagonistic arrangement for muscular contractions. They tend to enlarge following vigorous exercise, a phenomenon called muscular hypertrophy and are located around the body.

| Muscular System | |The Muscles: Each muscle is an organ, comprised of skeletal __muscle__ tissue, several ___connective____ tissue coverings, __nervous_ tissue to cause it | |to contract, and __blood___ to nourish it. | | Connective Tissue coverings: | |The muscle has several dense connective coverings.
Study Questions for muscle 1. Long fibers, striated, nucleus is peripherally located (multiple nuclei’s along the fiber) Muscular Fasica = Surrounds the individual muscles and groups of muscles (red, layer 1) Epimysium = Surrounds the muscles (dark blue, layer 2) Perimysium = Surrounds the fasciculi (light blue ring, layer 3) Endomysium = Surrounds the muscle fibers (light blue around orange, layer 4) Aponeurosis: Tendons that are broad and sheet-like 2. A muscle cell is also called a (Muscle Fiber). The plasma membrane of the muscle cell is called a (Sarcolemma). 3.
The human skeleton Is made up of 206 bones. The functions of the skeleton are to provide support, give our bodies shape, and provide protection to other systems and organs of the body, to provide attachments for muscles, to produce movement Joints A joint is the point where two or more bones meet. There are three main types of joints; Fibrous (immoveable), Cartilagenous (partially moveable) and the Synovial (freely moveable) joint. Fibrous joints Fibrous (synarthrodial): This type of joint is held together by only a ligament. Examples are where the teeth are held to their bony sockets and at both the radioulnar and tibiofibular joints.
Excitability: The ability of muscle tissue to receive a stimulus from the nervous system. Contractility: The quality that distinguishes muscle tissue from other types of tissue. 2.) Name the three types of muscle tissue found in the human body and briefly describe the primary function of each. Skeletal muscle: attached to the bones of the skeletal system.
