Accessory organs and tissues
The 3 types of Muscles
The smooth Muscle is self-initiated and has myogenic contraction to aid in the rhythmic movement of the organs. The smooth muscle has neurogenic contraction that requires neurons.
The skeletal muscle is used in locomotion. Each skeletal muscle acts as its own unit and is closely associated with connective tissue and is in control by the nervous system.
The cardiac muscle does not grow tired and maintains the circulation of blood. The cardiac muscle has mixed control and acts as a single functional unit.
Aponeurosis-Thin flat sheet
Fascia- Thin flat sheets of connective tissues that wrap and bind parts of the body together
Raphe- Junction of 2 muscles at a band of connective tissue to form a line of fusion, such as the linea alba.
When nervous stimuli applied beyond muscle's threshold level, contraction results and tensile force is generated, constituting the active state.
The attached bone and/or mass that must be moved represents the load- whether a muscle actually contracts depends on the relative balance between the tensile force of contraction and the load to be moved.
