Musculoskeletal System Flashcards
Musculoskeltal System
Includes muscles, bones, joints, tendons and connective tissue that function in support and movement of body parts and organs
Appendage
Any body part attached to a main structure
Articulation
Place of union between two or more bones; also called JOINT
Cancellous
Latticelike arrangement of bony plates occurring at the ends of long bones
Cruciate ligaments
Ligaments that cross each other, forming an X within the notch between the femoral condyles
Hematopoiesis
Production and development of blood cells, normally in the bone marrow
Muscle tissue
composed of contractile cells, or fibers, that provide movement of an organ or body part. Contribute to posture, produce body heat, and act as a protective covering for internal organs
Skeletal Muscles
Voluntary or striated muscles; are muscles whose action is under voluntary control.
Cardiac muscle
Found only in the heart. Unique for its branched interconnections, and make up most of the wall of the heart
Smooth muscle
Involuntary or visceral muscles, are muscles whose actions are involuntary. Controlled by autonomic nervous system
Fleshy attachments
Muscle fibers arise directly from bone.
Fibrous attachment
Connective tissue converges at the end of the muscle to become continuous and indistinguishable fro the periostum
Aponeurosis
When the fibrous attachment spans a large area of a bone
Tendon
When connective tissue fibers form a cord or strap. Penetrates the bone itself
Ligaments
flexible bands of fibrous tissue that are highly adapted for resisting strains and are one of the principal mechanical factors that hold bones together in a synovial joint
