Musculoskelatal System Flashcards
junction of two or more bones
joint
stabilize the bones and allow a
specific type of movement
joint
2 types of Joint
NONSYNOVIAL
SYNOVIAL
Identify the type of joint
* bones are connected by fibrous tissue, or cartilage
* may be immovable
NONSYNOVIAL
Identify the type of joint
* move freely
* the bones are separate from each
other and meet in a cavity filled with
synovial fluid (lubricant)
SYNOVIAL
They contract and produce skeletal
movement when they receive a stimulus from the central nervous system (CNS) → both involuntary and voluntary muscle function.
Skeletal muscles
tough fibrous portions of muscle that attach the muscles to bone.
Tendons
- sacs filled with friction-reducing synovial
fluid - they’re located in areas of high
friction such as the knee. - allow adjacent muscles or muscles and
tendons to glide smoothly over each
other during movement.
Bursae
Types of Joint Movement
- Moves forward
Protraction
Types of Joint Movement
- Moving backward
Retraction
Types of Joint Movement
- Bending
- decreasing joint angle
Flexion
Types of Joint Movement
- Straightening
- increasing the joint angle
Extension
Types of Joint Movement
- moving in a circular motion
Circumduction
Types of Joint Movement
- moving away from the midline
Abduction
Types of Joint Movement
- Moving toward the midline
Adduction
Types of Joint Movement
- Turning toward the midline
Internal Rotation
Types of Joint Movement
