Musculoskeletal Assessment Flashcards
1
Q
What are the 3 components of a Synovial joint
A
- Bones
- Synovial membrane
- Fibrous joint capsule
2
Q
Who tends to have increased soft tissue laxity?
A
Younger people & women
= increased ROM (double-jointed)
3
Q
How are fibrous joint capsules strengthened?
A
Strengthened by & in some cases continuous w/ ligaments extending from bone to bone
4
Q
Bones are covered by what type of cartilage?
A
Covered by articulate cartilage (a collagen matrix containing charged ions/water that allows it to change shape in response to pressure or load
5
Q
4 properties of Bones in the synovial joint
A
- do not touch
- joint articulation - freely movable w/in the limits of the surrounding ligaments
- covered by articulate cartilage
- separated by a synovial cavity that cushions joint movement
6
Q
Synovial membrane in the joint?
A
Lines the synovial cavity
- secretes a small amount of viscous lubricating fluid called SYNOVIAL FLUID
7
Q
What is the purpose of synovial fluid
A
Provides nutrition to the adjacent relative a vascular articulate cartilage
8
Q
What determines the direction & extent of joint motion
A
The shape of the articulating surfaces of synovial joints
as well as:
surrounding soft tissues
9
Q
What is a Bursae? And what does it do ?
A
Disc shaped synovial sacs
- facilitate joint action
- allow adjacent muscles or muscles & tendons to glide over each other during movement w/ reduced friction
10
Q
Where is the bursae located?
A
Between the skin & the convex surface of a bone or joint (pre-patellar bursa of the knee)
- in areas where tendons or muscles rub against bone, ligaments, & each other (subacromial bursa of the shoulder)
11
Q
What is a cartilaginous joint?
A
- fibrocartilaginous discs separate the bony surfaces
- fibrocartilage is compressible & shock absorber
12
Q
What surrounds a cartilaginous joint?

Surfaces on either side of the joint are covered w/ Hyaline cartilage
13
Q
What are 3 examples of Cartilaginous joints?

- Small amount of movement
14
Q
What is a Fibrous Joint and what does it consist of?
A
The sutures of the skull
- have intervening layers of fibrous tissue or cartilage that hold the bones together
- almost in direct contact
- no appreciable movement
15
Q
List the articular structures (4)
A
- The joint capsule & articular cartilage
- The synovial & synovial fluid

- Juxtaarticular bone
16
Q
