Ch 1-4 Flashcards
Exam 1
What are the 3 fibrous joint types?
- Syndesmosis-ligamentous
- Synarthrosis-Sutures
- Gomphosis-Tooth
- What are the 2 types of joint accessory motions (arthrokinematic/joint surface motions)?
- Component
2. Joint play
Define component motions.
- Component movements: Involuntary motions that occur as the result of voluntary ones. i.e. mechanorotation of the tibia with knee extension/lockdown mechanism.
Define the accessory motions
1. Joint mobilization
- Manipulation
- Passive oscilatory motions or sustained stretch applied by at a slow enough speed that the individual can stop the movement. i.e. r.o.m. or pnf stretch.
- Passive movement applied with short range and a very forceful thrust that cannot be stopped.
i. e. relocating a shoulder or chiropractic manipulation.
Osteokinematic
The movement of bones around a joint. Includes Isometric,isotonic, and isokinetic exercises.
Arthrokinematic
The manner in which adjoining surfaces move on each other during osteokinematic motion.

Usually bacterial infection of the bone usually through a break that goes through the skin.
Types of fibrous joints?
Des=distal

Sprain
Tearing of the fibers of a ligament

- Mild Tearing of a few fibers of a ligament. No loss of fx.
- Moderate Partial tearing of the of a ligament. Some loss of fx
- Severe Complete tearing of a ligament. Complete loss of fx.
Strain
Overstretching of a muscle or tear of the musculotendtinous juncture.
Capsular end-feel
Hard and leathery c slight give.

Define eversion/inversion
Eversion; The lifting and turning inward of the medial side of the foot.
Inversion; The raising and turning outward of the lateral side of the foot.
Linear motion?
Also called translatory; Occurs in a straight line from one location to another.
Angular motion?
Also rotory; All parts move in the same direction, through the same angle, at the same time, but not the same distance. IE elbow flexion.
Function of bone?
Support, protect, make blood cells.
What landmark of the 5th metatarsal often has a Jones fx?
