Question

question 16
which type of joint is found in the knee?
pivot joint
ball - and - socket joint
hinge joint
gliding joint
question 17
connective tissue is made of which three essential components?
matrix, ground substance, and fluid
cells, ground substance, and protein fibers
cells, ground substance, and carbohydrate fibers
collagen, ground substance, and protein fibers

Explanation:

Question 16

• Pivot joint allows rotation around an axis (e.g., neck).
• Ball - and - socket joint allows multi - directional movement (e.g., shoulder).
• Hinge joint allows movement like a door hinge (flexion and extension), which is characteristic of the knee.
• Gliding joint allows bones to glide over each other (e.g., wrist).

• Connective tissue has three main components: cells (e.g., fibroblasts), ground substance (amorphous gel - like substance), and protein fibers (e.g., collagen, elastic fibers). Matrix is a broader term that includes ground substance and fibers. Fluid is not a core component. Carbohydrate fibers are not a standard component. Collagen is a type of protein fiber, not a separate component from protein fibers.

Answer:

Hinge joint
