- Ball-and-socket (Correct answer)
- Hinge
- Pivot
- Saddle
Correct answer: Ball-and-socket
The glenohumeral joint is a ball-and-socket joint, allowing the greatest range of motion of any joint in the body.
Question 2: Which muscle is the primary hip flexor?
- Gluteus maximus
- Iliopsoas (Correct answer)
- Rectus femoris
- Tensor fasciae latae
Correct answer: Iliopsoas
The iliopsoas, composed of the iliacus and psoas major, is the primary hip flexor muscle.
Question 3: In which plane of motion does a standard bicep curl primarily occur?
- Frontal plane
- Transverse plane
- Sagittal plane (Correct answer)
- Coronal plane
Correct answer: Sagittal plane
A bicep curl occurs primarily in the sagittal plane, which divides the body into left and right halves.
Question 4: What is the term for the bony attachment point where a muscle's less-movable end connects?
- Insertion
- Origin (Correct answer)
- Belly
- Fascia

The origin is the proximal, less-movable attachment point of a muscle, typically on a stable bone.
Question 5: Which muscle group is the primary antagonist to the quadriceps?
- Calves
- Hamstrings (Correct answer)
- Adductors
- Gluteus medius
Correct answer: Hamstrings
The hamstrings act as the primary antagonist to the quadriceps during knee extension and flexion movements.
Question 6: What is the anatomical term for movement away from the body's midline?
