muscularskeletal review

skeletal frame work does what supports body, protects body
bone cell regulate the amount of calcium that is deposited osteocyte
looks solid but has precise cylinders of bone matrix compact
resembles a sponge with visible cavities spongy bone
produces red blood cells, platelets and 5 kinds of WBC Bone Marrow
arms, legs, hands,, not feet Long Bones
wrists, ankle bones Short Bones
ribs, shoulder blade, skull, hip bones Flat Bones
vertebrae, facial bones Irregular Bones
all joint surfaces are covered to provide a smooth surface Articulat cartilage
the rest of the bone is covered with this fibrous connective tissue membrane Periosteum
some bones contain and protect this hemopoetic tissue that produces blood cells Red Bone Marrow
produces bone matrix Osteoblasts
reabsorbes and dissolve the minerals of bone matrix Osteoclast
in the embryo the arms and legs are made up of cartilage
the 2 divisions of the skeleton AXIAL- rib cage , skull, vertebra, APPENDICULAR-, arms,legs,shoulder girdle, pelvic girdle
the 3 vitamin that affect growth and maintenance of bone A-C-D
it is lose without the normal stress on bones Calcium
the 3 bones of the ear Incus, Malleus, Stapes
it is protected and contained within the verterbral column which connectsthe trunk and the head Spinal cord
the 1st cervical vertebra ATLAS
the 2nd cervical vertebra AXIS
the sternum is made up of 3 parts Manubrium, body, xiphoid process
Scapula is the shoulder bone
Clavicle is the collar bone
articulates with the humerus to form the elbow Ulna
form with the femur to form the knee Tibia
forms the heal calcaneus
immovable joint Synarthrosis
slight movement in joint Ampharthrosis
Lots of movement in joint Diarthrosis
all diarthrosis joints are Synovial Joints
covers the smooth bone surface at the joint Articular Cartilage
made of fibrous connective tissue enclosed the joint Joint Capsule
lines the joint capsule secreting synovial fluid into cavity Synovial membrane
is thick, slippery and prevents friction within the cavity Synovial Fluid
small dsacks of synovial fluid between joints and tendons Bursae
Muscular system has 2 functions Movement of the body, produces heat
muscle cells are specialized for one purpose Contraction
Tendons merg with Fascia of muscle, Periosteum of bones
Antagonistis Muscles have opposite functions
Synergistic Muscles have the same functions (work together)
Isotonic bring about movement
Isometric without movement
brain knows where the muscles are and what they are doing without having to look Muscle Sense
LACTIC ACID builds up in muscle tissue Muscle Fatigue
The 2 contraction proteins in a muscle fiber are Myocin , Actin
FLEXION ti decrease the angle of a joint
EXTENSION to increase the angle of a joint
ADDUCTION to move closer to the midline
ABDUCTION to move further away from midline
PRONATION to turn the palms down (facing the back)
SUPINAATION to turn the palms up (facing towards the front)
DORSIFLECTION to elevate the foot
PLANTAR FLEXION to lower the foot (point the toes)
ROTATION to move a bone around its longitudinal axis
colles fracture from falling and catching self
Basiliar fracture fracture at the base of the skull, usually motor vehicle accident
Potts fracture lower tibia and fibula
Medial Meniscus the larger more restrictive and more liable to be injured
ROM range of motion
Meniscus of the knee hjoint is attached to these ligaments Posterior curciate
Instrument to examine interior of a joint using a tube like instrument Arthroscope
the diet change for GOUT less protein and more fluids
causes LYME Disease Borrelia Burgdorferi
Inflammation of the PERIOSTEUM and EXTENSOR MUSCLES Shin Splints
responsible for 90% of the osteomyelitis infections Strephlococus
suture of the divided ends of a tendon Tenorrhapy
common injection sites Deltoid muscle, Gluteus Medius muscle, Vastus Lateraus muscle
disorder of uric acid metabolism causing deposits of uric acid nodules formation in tissue Gout
disorder effecting the size and shape of bones Osteoitis Deformins
Inderited condition featuring abnormal connective tissue with weakness of blood vessles & skeletal defects, long limbs, spider like fingers Marfin Syndrome
loss of bone density Osteoporosis
type of arthritis that results from break down and loss of cartliage to one or more joints Osteoarthritis
defective mineralization of bones of adults osteomalacia
defective mineralization of bones, in children impacts growth Rickets
localized enlargement of the inner portion of the 1st MTP joint with an inward position of the great toe Hallus Vagus-BUNION
degeneration of the cartilage of the 1st MTP joint causing stiff great toe and develoopment of bone spurs Hallus Rwgidis
Imflammation, scaring thickening shrinkage of capsule surrounding nornmal shoulder joint causing linited ROM (frozen shoulder) Adhesive Capulitis
acute partial tear of a ligament classified 1st, 2nd,23rd, degree Sprain
stretching of tendon, muscle or other tissue beyond it functionsl capacity Strain
the two divisions of the skeleton AXIAL --- APPENDICULAR
