Here is the solution to the worksheet titled
"Types of Joints" with explanations for each answer:
---
1. Name a location in the body where you would find a ball and socket joint.
Answer: Hip
*(Other possible answer: Shoulder)*
Explanation:
A
ball-and-socket joint allows for a wide range of motion, including rotation, flexion, extension, abduction, adduction, and circumduction. The
hip joint (between the femur and acetabulum of the pelvis) is a classic example. The
shoulder joint (between the humerus and scapula) is another example.
---
2. Name a location in the body where you would find a hinge joint.
Answer: Elbow
*(Other possible answers: Knee, Ankle)*
Explanation:
A
hinge joint allows movement in one plane, like a door hinge—flexion and extension. The
elbow joint (between the humerus and ulna) is a prime example. The
knee and
ankle joints are also hinge joints.
---
3. Name a location in the body where you would find a gliding joint.
Answer: Between the tarsal bones in the foot
*(Other possible answers: Between carpal bones in the wrist, or between vertebrae)*
Explanation:
A
gliding joint (also called a plane joint) allows bones to slide over one another with limited motion. These are found between the
tarsal bones in the foot,
carpal bones in the wrist, and
vertebrae in the spine.
---
4. Name a location in the body where you would find a suture, or immovable joint.
Answer: Skull (between cranial bones)
Explanation:
A
suture joint is an
immovable (fibrous) joint that connects the bones of the skull. These joints are held together by dense connective tissue and do not allow movement. They help protect the brain and maintain the shape of the skull.

✔ Summary Table:
| Joint Type | Example Location |
|--------------------|----------------------------------|
| Ball-and-socket | Hip, Shoulder |
| Hinge | Elbow, Knee |
| Gliding | Foot (tarsals), Wrist (carpals) |
| Suture (immovable) | Skull (cranial bones) |
