LAB 6 - Joints and Muscles Flashcards
What 2 bones make up the should joint and what is their features that articulate?
Hemispherical head of humerus articulates with glenoid cavity of scapula.
What is the groove called that a large muscle tendon passes over underneath the humerus?
intertubercular sulcus.
Where does the tendon come from that is under the humerus what why is it important?
from the biceps brachii
important stabilizer of the shoulder
On what bone do rotator muscles originate and insert within the shoulder?
Originate = scapula Insert = humerus
What muscle is present on the anterior surface of the scapula, inferior to the corocoid process?
subscapularic
What rotator cuff muscle is in between your thumb and fingers?
supraspinatus
What is the action of the supraspinatus rotator cuff muscle?
Aids deltoid in abduction of arm;
resists downward slippage of humeral head when arm is relaxed or carrying weight.
What muscle is superficial to the supraspinatus rotator cuff muscle and is palpable between tour thumb and fingers?
Trapezius
What is the action of the deltoid muscle?
anterior fibers flex and medially rotates arm;
lateral fibers abduct arm;
posterior fibers extend and laterally rotate arm
What two bones articulated to form the knee joint?
tibia and femur
What tendon covers the patella?
quadriceps femoris tendon
What is the same piece CT between the patella and the tibia?
Patella ligament
What is the bone feature of the tibia to which the patella ligament inserts?
tibial tuberosity
What is the lateral ligament that stabilizes the knee?
fibular collateral ligament
What is the lateral ligament that stabilizes the knee?
tibial ligament
What is the name of the ligament that attaches the anterior tibia with the posterior femur?
anterior cruciate ligament
What is the name of the ligament that attaches the posterior tibia with the anterior femur?
posterior cruciate ligament
What bone features are the origins of the gastrocnemius?
epicondyles
What are the structures that provide cushion between the tibia and femur?
medial and lateral meniscus
