Motor-Musculoskeletal Flashcards
It is the body’s central framework
Skeletal system
the skeletal system consists of _____ and ______
bones and connective tissue (cartilage, ligaments, tendons)
what is the primary function of skeletal system
- structure
- protection
- act as levers
- produce blood cells
- store calcium
Organ system consisting of skeletal, smooth, & cardiac muscles.
muscular system
muscular system permits ______ of the body, maintains _______, and _______ blood throughout the body.
- movement
- posture
- circulates
what is the primary function of muscular system
- allow movement and position
- produce heat
point of articulation of two bones; provide ROM
joint
connects bone to bone
ligament
connect muscle to bone
tendon
supports and shapes; acts as a shock absorber
cartilage
sacs filled w/ synovial fluid; cushion & reduce friction
between joints
● Bursae:
type of joint that permits rotation in one axis ( supinates, pronates, rotates)
pivot
type of joint that allows FLEXION and EXTENSION
hinge
type of joint that can be FLEXED, EXTEND, ABDUCT, ADDUCT and CIRCUMDUCT. also called “Egg-in-spoon joint”
condyloid
longitudinal type of joint with bone moving around a central axis
without any displacement from tat axis
axis
moves across many possible axes (flexion, extension, internal rotation, external rotation, abduction, adduction & circumduction)
ball and socket
moves across many axes; articular surface are flat, & one bone rides over the other in many directions (limited in many directions)
plane/ gliding
type of joint that can only abduct, adduct, opposition and reposition
saddle
in assessing the musculoskeletal system, what are the possible abnormal findings
- Symmetry/Asymmetry –
- Skin Color and Appearance
- Rash
- Ulcers
- Lack of sweating
- Hair abnormalities
- Warmth and heat
- Swelling including effusions, nodules
- Inflammatory findings like synovial and periarticular thickening.
what are the common problems of the musculoskeletal system
pain
weakness
stiffness
balance and coordination
it is usually associated with movement
muscle pain
muscle pain can be caused by ______ or _______
cramping or soreness
what are the possible cause of bone pain?
fracture
RA (rheumatoid arthritis)
Osteoarthritis
bone pain can be felt as ______, ________, ________ pain
deep, dull, throbbing
RA and osteoarthritis is experienced by joint pain and stiffness, what is the difference between them?
- RA worse in the morning
- Osteoarthritis worse at the end of the day
it is associated with certain diseases that migrates from muscle to groups of muscles
muscle weakness
how do we assess muscle weakness?
- know symptoms patter
- ask pt if weakness interferes with ADL
T OR F: is it necessary to ask the patient if the muscle weakness interferes with their ADL?
T
what are the 2 SYMPTOM PATTER for muscle weakness
- proximal weakness
- distal weakness
a. Proximal weakness -is usually a _________
b. Distal weakness - is usually a
- myopathy
- neuropathy
what ADLS are affected when there is PROXIMAL weakness of UPPER extremities
difficulty lifting objects or combing hair
what ADLS are affected when there is PROXIMAL weakness of LOWER extremities
difficulty with walking & crossing the knees.
what ADLS are affected when there is DISTAL weakness of UPPER extremities
difficulty in dressing or turning the knob
it is the most common musculoskeletal complaint
stiffness
