lecture 13 Flashcards
1
Q
suture
A
- The lines between the bones in the skull. Once formed and fused they are immovable joints
2
Q
gomphosis
A
- Peg and socket joint. Very short fibers that very tightly hold the teeth in place. Very little movement as long as it remains healthy.
in the mandible and maxilla
3
Q
syndesmosis
A
- Based on how long the fibers are tells how much movement there will be. The shorter the fibers the less movement. If the fiber is long, you may get a little bit of movement.
- Is what allowing us to twist our legs from side to side.
4
Q
cartilaginous joints
A
- Bones are joined directly by cartilage, no bone cavity. Typically, do not allow much movement.
- are joints where the bones are joined by cartilage
5
Q
synchondrosis
A
- Where bones are connected by hyaline cartilage. Found in connections between the ribs and the sternum. (shown is the first costal cartilage joint) Will typically have little to no movement.
- Another example is the epiphyseal growth plate. No movement occurs.
6
Q
symphysis
A
- A joint that is untied by fibrocartilage. Typically found in areas that have a lot of stress on them.
- The intervertebral disks can have some movement (is what helps us to move our spine). The pubic symphysis, the plate between the two os coxae.
7
Q
synovial joints
A
- Bones that are separated by a fluid-filled joint cavity (filled with synovial fluid). Like my labrum tear, allows for a lot of movement
8
Q
articular discs/meniscus
A
- Acts as a shock absorber and provides stability. Is a crescent shaped structure found in certain joints, especially the knee. A plate of fibrocartilage between the bones to help protect from wear and tear.
9
Q
bursa
A
- A small fibrous sac filled with synovial fluid. Tend to find in areas where there are tendons, muscle, skin, and bone, all in a tight area. Its job is to help prevent rubbing and friction within that joint.
- Bursitis – inflammation or infection of the bursa. (pretty common in the shoulder, elbow, and hip joints.)
10
Q
tendon sheath
A
- An elongated bursa. Instead of being a sack, it is a long tube like structure that is wrapped around tendons. Found where tendons are in tight spaces.
- A lot in the carpal tunnel area.
11
Q
synarthroses
A
no movement
12
Q
ampiarthroses
A
little movement
13
Q
diarthroses
A
full movement
ankle joint, in between finger bones
14
Q
luxation
A
joint dislocation
- the more moveable something is the more likely it is to dislocate
15
Q
gliding
A
when flat surfaces between the (tarsals for example) bone which allows for the bones to glide by one another
