Connective tissue is present in all muscles as fascia. Enclosing each muscle is a layer of connective tissue known as the epimysium; enclosing each fascicle is a layer called the perimysium and enclosing each muscle fiber is a layer of connective tissue called the endomysium. Muscle fibers are the individual contractile units within a muscle. A single muscle such as the biceps brachii contains many muscle fibers.
The anatomy of muscles includes gross anatomy which comprises all the muscles of an organism and microanatomy which comprises the structures of a single muscle. Muscle tissue is a soft tissue and is one of the four fundamental types of tissue present in animals. There are three types of muscle tissue recognized in vertebrates: • Skeletal muscle or “voluntary muscle” is anchored by tendons (or by aponeuroses at a few places) to bone
Wed Aug 17 2005 14:30:00 GMT-0400 (Eastern Daylight Time) · Skeletal muscles are the only voluntary muscles the only ones that we can choose to move. The cardiac muscle is the muscle in the heart. When this muscle contracts it pushes blood through the circulatory system. The cardiac muscle is not voluntary.
Thus muscle tissue can be described as being one of three different types: Skeletal muscle striated in structure and under voluntary control is anchored by tendons (or by aponeuroses at a few places) to bone and is used to effect skeletal movement such as locomotion and to maintain posture. …
