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

- moving in a circular motion
Circumduction

- moving away from the midline
Abduction
Types of Joint Movement
- Moving toward the midline
Adduction

Tests for carpal tunnel syndrome
- Tinel’s sign
- Phalen’s Maneuver
Identify which test for carpal tunnel syndrome is being described
- done by lightly percussing transverse carpal ligament over median nerve where palm and wrist meet
- positive when action produces numbness and tingling into palm and finger
Tinel’s Sign
Identify which test for carpal tunnel syndrome is being described
- have patient’s back of hands together and flex downwards at 90 degree angle
- if pain and numbness present then its positive
Phalen’s maneuver

Grading of Muscle Strength
5/5 - Full ROM against gravity and resistance
4/5 - Completes ROM against gravity with moderate resistance
3/5 - ROM completed against gravity only
2/5 - Full ROM with gravity eliminated (Passive motion)
1/5 - Patients attempt at muscle contraction palpable with no joint movement
0/5 - No evidence of muscle contraction
Common Musculoskeletal Abnormalities
- plantar flexion of foot with toes bent toward instep
- its results from weakness or paralysis of dorsiflexor muscle
- may stem from prolonged immobility
Foot Drop
Common Musculoskeletal Abnormalities
- strong painful muscle contractions
- commonly occur on the calf
- result from simple muscle fatigue, exercise, electrolyte imbalance, neuromuscular disorders, and pregnancy
Muscle Spasms
Common Musculoskeletal Abnormalities
- aka muscle wasting
- results from denervation or prolonged muscle disuse
- also results from aging
Muscle Atrophy
Common Musculoskeletal Abnormalities
- abnormal crunching or grating heard and felt on the joint
- occurs for patients with rheumatoid arthritis or osteoarthritis
- occurs when patients broken pieces of bones rub together
Crepitus
Common Musculoskeletal Abnormalities
- result from malfunction in cerebral hemispheres, brain stem, spinal cord, nerve roots, peripheral nerves, or myoneural junctions within muscle
Muscle Weakness

Pallor
Pulse
5 P’s of Classic Signs of Compartment Syndrome
Pain
Pallor
Paresthesias
Paralysis
Pulselessness
Theses nodes are typically seen in patients with osteoarthritis
Heberden’s and Bouchard’s Nodes
its a chronic systemic inflammatory immune disorder commonly affecting bilateral joints of fingers, wrists, elbows, knees, or ankles as well as surrounding muscle, tendons, ligaments, and blood vessels
Rheumatoid Arthritis
It is a metabolic disorder where uric acid deposits in the joints causing joints to become painful, arthritic, red, and swollen. Skin temperature may be elevated due to irritation and inflammation
Gout
A round enlarged fluid filled cyst commonly found on dorsal side of wrist. It may be nontender when it develops near a tender sheath. May be painful and may limit joint mobility
Ganglion
A group of congenital disorders characterized by progressive symmetrical wasting of skeletal muscles without neural or sensory defects
Muscular Dystrophy
its when the patient is unable to lift their trunk without using hands and arms to brace and push. it indicates pelvic muscle weakness
