Pojęcia w tym zestawie(18)
Shoulder joint type
The shoulder joint is a ball-and-socket joint, allowing a wide range of motion.
Hip joint type
The hip joint is also a ball-and-socket joint, but it is more stable than the shoulder.
What connects the shoulder to the torso?
The clavicle (collarbone) is the bony structure connecting the shoulder to the torso.
What connects the hip to the torso?
The pelvis connects the hip joint to the torso, providing stability.
True or false: The shoulder has a deeper socket than the hip.
False, because the hip has a deeper socket (acetabulum) for stability.
Range of motion comparison
The shoulder has a greater range of motion than the hip joint.
Muscles around the shoulder
Key muscles include the rotator cuff, deltoid, and pectoralis major.
Muscles around the hip
Key muscles include the gluteus maximus, iliopsoas, and quadriceps.
Fill in the blank: The shoulder joint is more ______ than the hip joint.
mobile
Which joint allows for overhead movements?
The shoulder joint allows for overhead movements like raising the arm.
Difference between bursa in shoulder and hip
The shoulder has several bursae that reduce friction; the hip primarily has one major bursa.
True or false: The shoulder is more prone to dislocations than the hip.
True, because the shoulder's joint structure is less stable.
What is the primary function of the rotator cuff?
The rotator cuff stabilizes the shoulder and allows for arm rotation.
What is the primary function of the hip flexors?
The hip flexors, such as the iliopsoas, allow for hip flexion and leg movement.
What is the labrum?
The labrum is a cartilage structure that deepens the socket in both the shoulder and hip joints.
Comparison of injury types
Shoulder injuries often include rotator cuff tears; hip injuries often include labral tears.
Key ligament in the shoulder
The glenohumeral ligaments provide stability to the shoulder joint.
Key ligament in the hip
The iliofemoral ligament provides stability to the hip joint.
