The gliding motion of the carpal bones uses _____ joints.
A. Hinge
Hinge joints allow movement in one plane, such as flexion and extension, seen in the elbow and knee. They do not permit gliding motions.
B. Plane
Plane joints are the correct answer. They allow bones to slide past each other in any direction along the plane of the joint. The carpal bones in the wrist articulate via plane joints, enabling gliding movements.
C. Ball-and-socket
Ball-and-socket joints allow multi-directional movement and rotation, such as in the shoulder and hip. They are not involved in the gliding motion of carpal bones.
D. Condyloid
Condyloid joints permit movement in two planes, such as flexion/extension and abduction/adduction. They are found in the wrist but not between carpal bones.
E. Pivot
Pivot joints allow rotational movement around a single axis, such as the joint between the atlas and axis vertebrae. They do not facilitate gliding.

Ossification is the process of:
A. Bone remodeling after an injury
Bone remodeling after an injury is part of the healing process but is not synonymous with ossification. Remodeling involves both bone resorption and formation but is a later stage in bone repair.
B. Making a cartilage model of the fetal bone
Making a cartilage model of the fetal bone refers to endochondral ossification’s early stage, but ossification itself is the process of converting that cartilage into bone.
C. Bone destruction to release calcium
Bone destruction to release calcium is known as bone resorption, primarily carried out by osteoclasts. It is not the same as ossification.
D. Bone formation
Bone formation is the correct answer. Ossification is the process by which new bone is formed, either by replacing cartilage (endochondral ossification) or forming directly from mesenchymal tissue (intramembranous ossification).
E. Making collagen fibers for calcified cartilage
Making collagen fibers for calcified cartilage is a component of cartilage development but does not define ossification. Ossification involves mineralization and the transformation of cartilage or mesenchyme into bone.

Which of the following bones in the face are the only ones that aren't a pair of bones?
A. Zygomatic and nasal
Both the zygomatic and nasal bones are paired. Each side of the face has one zygomatic bone and one nasal bone, making them bilateral structures.
B. Mandible and maxilla
The mandible is unpaired, but the maxilla is paired. Each side of the face has a maxillary bone, so this combination is not entirely correct.
C. Mandible and vomer
Mandible and vomer are the correct answer. Both are unpaired bones in the facial skeleton. The mandible forms the lower jaw, and the vomer forms part of the nasal septum. They are midline structures and exist as single bones.
D. Lacrimal and maxilla
Both the lacrimal and maxilla are paired bones. Each orbit has a lacrimal bone, and each side of the face has a maxilla.
E. Palatine and vomer
The palatine bones are paired, while the vomer is unpaired. This combination is partially correct but not as accurate as choice C.

Connective tissue sacs lined with synovial membrane that act as cushions in places where friction develops are called:
A. Tendons
Tendons connect muscles to bones and transmit force during contraction. They do not act as cushions or reduce friction.
B. Bursae
Bursae are the correct answer. These are small fluid-filled sacs lined with synovial membrane that reduce friction between moving structures such as tendons and bones or skin and bones. They are commonly found near joints like the shoulder, elbow, and knee.
C. Menisci
Menisci are fibrocartilaginous pads found in certain joints like the knee. They help distribute weight and improve joint stability but are not fluid-filled sacs.
D. Joint cavities
Joint cavities are spaces within synovial joints that contain synovial fluid. While they allow movement, they are not separate cushioning structures like bursae.
E. Ligaments
Ligaments connect bones to other bones and stabilize joints. They do not serve as cushions or reduce friction.
