Study Notes
Muscle Tissue Properties
- Muscle tissue is excitable, contractible, extensible, and elastic
- Excitability refers to the ability to respond to stimuli
- Contractibility refers to the ability to contract
- Extensibility refers to the ability to be stretched without tearing
- Elasticity refers to the ability to return to its normal shape
Muscle Tissue Structure
- Muscle tissue comprises specialized cells called muscle cells or myocytes (muscle fibers)
- Myocytes contain protein filaments known as actin and myosin
- Muscle tissue is described as striated or non-striated based on the presence or absence of striations
- Striations are formed by the arrangement of actin and myosin filaments within myocytes
Skeletal Muscle
- Skeletal muscle is the most common type of muscle tissue in the body
- Skeletal muscle cells are elongated, multinucleate, and non-branching
- Skeletal muscle cells fuse to form syncytia
- The fusion of myoblasts forms skeletal muscle cells/myocytes
- Skeletal muscle is often referred to as 'voluntary' muscle, but it is involved in both conscious and subconscious movements
Cardiac Muscle
- Cardiac muscle is striated and contains contractile proteins arranged into sarcomeres
- Cardiac muscle cells are shorter and broader than skeletal muscle cells, and branched at their ends
- Cardiac muscle cells are typically uninucleate, sometimes binucleate, and the nucleus is centrally located
- Striations in cardiac muscle are less defined than in skeletal muscle
- Cardiac muscle cells are surrounded by loose connective tissue, similar to endomysium, but less organized
Smooth Muscle
- Smooth muscle is found in the walls of tubular structures and hollow organs
- Smooth muscle cells are smaller and shorter than skeletal muscle cells, and uninucleate
- Smooth muscle cells are spindle-shaped with long tapered ends and are packed together
- Smooth muscle is subject to subconscious/involuntary control
