Questions with Rationales
1. A joint held together by dense connective tissue with many collagen fibers,
found where bones are in close contact, is called a:
Answer: Fibrous joint
Rationale: Fibrous joints (synarthroses) are immovable or slightly movable joints
where bones are united by fibrous connective tissue. Examples include sutures of
the skull, syndesmoses, and gomphoses.
2. Name the three types of fibrous joints.
Answer: Syndesmosis, suture, gomphosis
Rationale: Syndesmosis (bones bound by interosseous membrane/ligament),
suture (thin sutural ligament between skull bones), gomphosis (cone-shaped
process in a socket, e.g., tooth in alveolus).
3. Which type of fibrous joint has bones bound by a sheet of dense connective
tissue (interosseous membrane) or a bundle of dense connective tissue
(interosseous ligament)?
Answer: Syndesmosis
Rationale: Syndesmosis allows slight movement (amphiarthrosis). Example: distal
tibiofibular joint held by interosseous membrane.
4. A thin layer of connective tissue called the sutural ligament connects bones in
which type of fibrous joint?
Answer: Suture
Rationale: Sutures are unique to the skull. They are immovable (synarthrotic) in
adults but allow growth during childhood.
, 5. Which joint is described as a cone-shaped bony process fitting into a socket?
Answer: Gomphosis
Rationale: A gomphosis is a peg-and-socket fibrous joint, such as a tooth in its
alveolar socket, held by the periodontal ligament.
6. What are the two types of cartilaginous joints?
Answer: Synchondrosis and symphysis
Rationale: Cartilaginous joints unite bones with cartilage. Synchondrosis uses
hyaline cartilage (e.g., epiphyseal plates), symphysis uses fibrocartilage (e.g.,
intervertebral discs).
7. Bands of hyaline cartilage unite bones in which type of cartilaginous joint?
Answer: Synchondrosis
Rationale: Synchondroses are immovable (synarthrotic) joints. Examples include
the joint between the first rib and sternum, and the epiphyseal plate in growing
bones.
8. The joint between the bodies of adjacent vertebrae (intervertebral discs) is an
example of which type of joint and functional classification?
Answer: Symphysis; amphiarthrotic
Rationale: Symphyses are cartilaginous joints with fibrocartilage. They allow slight
movement (amphiarthrosis) and absorb shock. Intervertebral discs and pubic
symphysis are examples.
9. Which class of joints is always diarthrotic (freely movable)?
Answer: Synovial joints
Rationale: All synovial joints have a joint cavity, synovial fluid, articular cartilage,
and a fibrous capsule. They permit a wide range of movements.
