Questions and CORRECT Answers
Articulation (Joint) - CORRECT ANSWER- ✔✔
Fibrous Joints - CORRECT ANSWER- ✔✔Lack a synovial cavity and articulating bones are
held closely by dense irregular connective tissue. Permit little to no movement.
- Suture: thin layer of dense irregular connective tissue. between the bones in the skull.
Decrease changes of fractures.
- Syndesmosis: greater distance between the articulating surfaces and more dense irregular
tissue than in a suture. Typically arranged in a bundle, allowing limited movement.
- Gomphosis: cone shaped peg fits into a socket. e.g. roots of teeth and sockets.
- Interosseous membranes: substantial sheet of dense irregular tissue that binds neighbouring
long bones and permits slight movement. e.g. between the radius and luna, and tibia and
fibula.
Cartilaginous Joints - CORRECT ANSWER- ✔✔- Synchondrosis: connecting material is
hyaline cartilage. e.g. epiphyseal plate. it is an immovable joint, and bone replaces it after
elongating. e.g. between first rib and sternum, which also ossifies.
- Symphysis: ends of articulating bones are covered in hyaline cartilage, but a broad flat disc
of fibrocartilage connects the bones. All of these joints occur in the middle of the body: e.g.
pubic between anterior surfaces of the hip bones. It is a slightly movable joint.
Synovial Joints - CORRECT ANSWER- ✔✔- Synovial (joint) cavity: between articulating
bones. Considerable movement at joint.
- Articular cartilage: layer of hyaline cartilage covering the bones at a synovial joint. reduces
friction
- Articular capsule: composed of two layers: outer fibrous membrane and inner synovial
membrane.
- Fibrous membrane: dense irregular connective tissue that attaches the periosteum of
articulating bones.
