ANAPHY SHET Flashcards
Contraction of skeletal muscles is responsible for the overall movements of
the body.
Body movement
Skeletal muscles constantly maintain tone, which keeps us sitting or
standing erect.
Maintenance of posture
Skeletal muscles of the thorax are responsible for the movements necessary for
respiration.
Respiration
When skeletal muscles contract, heat is given off as a by-product.
Production of body heat -
Skeletal muscles are involved in all aspects of communication, such as
speaking, writing, typing, gesturing, and facial expression.
Communication
The contraction of smooth muscle within the walls of
internal organs and vessels causes constriction of those structures.
Constriction of organs and vessels
The contraction of cardiac muscle causes the heart to beat, propelling blood to all
parts of the body.
Heart beat
Ability of a muscle to shorten with force.
Contractility
Capacity of muscle to respond to a stimulus
Excitability
Function of Skeletal Muscle
- Maintain body temperature.
- Maintain Posture
- Movement
- Protect internal organs
Muscle can be stretched to its normal resting lengthand beyond to a limited degree.
Extensibility
- Ability of muscle to recoil to original resting length after stretched.
- Elasticity
flexible but unbendable cord of strong fibrous collagen tissue attaching a muscle
to a bone.
TENDON
Sites of Muscle Attachment
-bones
-cartilages
-connective tissue coverings
TENDON
APONEUROSES
sheet of pearly-white fibrous tissue that takes the place of a tendon in
sheet-like muscles having a wide area of attachment.
