Anatomical Terms of Muscle[edit | edit source]
The Anatomical Terms of Muscle are used to describe the various components, processes, and functions of the muscular system in the human body. These terms are derived from anatomical terminology and are standardized to avoid confusion. They are widely used in the fields of biology, medicine, and physiology.
Structure of Muscles[edit | edit source]
Muscles are complex structures composed of muscle cells, also known as myocytes. Each myocyte contains myofibrils, which are made up of sarcomeres, the basic unit of muscle contraction. The sarcomeres are composed of two types of filaments: thick filaments made of myosin and thin filaments made of actin.
Types of Muscles[edit | edit source]
There are three types of muscles in the human body: skeletal, cardiac, and smooth muscles.
Skeletal Muscles[edit | edit source]
Skeletal muscles are attached to bones and are responsible for voluntary movements. They are composed of long, cylindrical cells and have a striated appearance under the microscope.
Cardiac Muscles[edit | edit source]
Cardiac muscles are found in the heart and are responsible for pumping blood throughout the body. They are also striated, but unlike skeletal muscles, their contractions are involuntary.
Smooth Muscles[edit | edit source]
Smooth muscles are found in various organs and structures such as the esophagus, stomach, intestines, bronchi, uterus, urethra, and blood vessels. Unlike skeletal and cardiac muscles, smooth muscles are not striated and their contractions are involuntary.
Muscle Contraction[edit | edit source]
Muscle contraction is the process by which muscles produce force and change length. This process is regulated by the nervous system through the release of acetylcholine at the neuromuscular junction.
