PHTY100 Lecture Notes - Lecture 2: Rectus Femoris Muscle, Iliopsoas, Fibrocartilage
Document Summary
Ligaments-strong capsule reinforced by a number of ligaments. Ball & socket joint (multiaxial) allows the hip to be mobile. Action: movement produced when a muscle contracts concentrically in isolation. Synergist: cancels out the unwanted bits of the mover. Acceleration phase: extend at hip flex at knee. The predominant movement at the hip is hip flexion. Iliopsoas: the most efficient (used first requiring less synergism: pectineus: hip adduction, tensor fascia lata: hip abduction and internal rotation rectus femoris: knee extension. The muscle that requires least synergism will be recruited (used) Muscles that cross one joint are recruited first. Any muscle with a line of pull parallel to neck of femur. 3. 10 identify and describe the functions of the: Fascia lata (cylindrical, deep fascia lata of the thigh) A fascia is defined as a sheet or band of fibrous tissue lying deep to the skin that lines, invests and separates structures within the body. Deep fascia: envelopes muscles, bones and neurovascular structures.
