Which hypertonic muscle might result in rotation of the ilium causing a functional short leg
- A.
Biceps femoris
- B.
Iliopsoas
- C.
Rectus abdominis
- D.
Gluteus medius
Correct Answer
B. IliopsoasExplanation
The iliopsoas muscle is responsible for flexing the hip joint and can cause rotation of the ilium. When this muscle becomes hypertonic or overly tight, it can pull on the ilium, causing it to rotate. This rotation can result in a functional short leg, where one leg appears shorter than the other due to the misalignment of the pelvis. Therefore, the hypertonicity of the iliopsoas muscle can explain the rotation of the ilium and the functional short leg.Rate this question:

Chronic inflammation and fibrosis of the rotator cuff musculature could result in
- A.
Hyper-mobility of the shoulder
- B.
Antalgic gait
- C.
Frozen shoulder
- D.
Winged scapula
Correct Answer
C. Frozen shoulderExplanation
Chronic inflammation and fibrosis of the rotator cuff musculature can lead to frozen shoulder. Frozen shoulder, also known as adhesive capsulitis, is a condition characterized by stiffness, pain, and limited range of motion in the shoulder joint. The inflammation and fibrosis cause the shoulder joint capsule to thicken and tighten, resulting in the loss of movement. This condition can be caused by various factors, including injury, overuse, and certain medical conditions. Treatment often involves physical therapy, pain management, and in some cases, surgical intervention.Rate this question:

Because of their lack of vascularity, the following tissue is known to heal quite slowly
- A.
Epithelial
- B.
Fibrous connective
- C.
Muscle
- D.
Bone
Correct Answer
B. Fibrous connectiveExplanation
Fibrous connective tissue is known to heal quite slowly because it has a limited blood supply. Vascularity refers to the presence of blood vessels, which are responsible for delivering oxygen and nutrients to tissues and removing waste products. Fibrous connective tissue, such as tendons and ligaments, has a low vascularity compared to other tissues like epithelial tissue. This limited blood supply slows down the healing process, making fibrous connective tissue prone to prolonged recovery times.Rate this question:
