Alterations in Musculoskeletal Integrity - correct answer- Negative effect on ability to perform activities
of daily living, communicate, participate in recreational activities
- source of frustration and pain
Types of muscle tissue - correct answer- smooth
- cardiac
- skeletal
How many skeletal muscles in the body? - correct answermore than 640
- critical for physical mobility
- attach to bones via tendons
- muscle contraction causes movement of skeletal bones
How many bones in the body? - correct answer206
Axial skeleton - correct answerribs, sternum, vertebral column, skull
Appendicular skeleton - correct answer- pectoral gridles, pelvic gridle, upper and lower limbs

,NU 272 Exam 2 Questions With Complete Solutions
- supporting soft tissues
- protecting vital organs
- providing a point of attachment for muscles
- storing minerals
- forming blood cells
Joints - correct answer- formed when two or more bones meet
- hold the skeleton together while providing mobility
- structural and functional classifications generally interrelated for most joints
Joints that fall outside the general classification - correct answerEpiphyseal plate in children
(cartilaginous)
Ligaments, tendons, and cartilage - correct answer- connective tissues composed of differing amounts of
collagen fibers, other structural components
- connect bones to other bones to form a joint
- strengthen, stabilize joint
- may limit mobility of some joints
Tendons - correct answer- connect bones to muscles for movement
- carry contractile forces from muscle to bone --> movement
Cartilage - correct answer- flexible connective tissue
- less flexible than muscle, not as rigid as bones
- does not contain blood vessels (unlike ligaments, tendons)
Alterations to mobility - correct answer- arthritis
- fractures
- neurologic disorders

-protrusion of bone out of skin
- limited mobility
- ice pack to limit swelling
- pharmacologic therapy to reduce pain and swelling and prevent infection
- immobilization with a splint, brace, cast, or traction
- surgery to stabilize bone or replace fractured bone
Herniated Disk - correct answer- a spinal column disk that slips out of place or ruptures
- back pain that spreads to butt and legs (herniated disc in lower back) or to shoulders and arms
(herniated disc in upper back)
- tingling or numbness
- muscle spasms or weakness
- limited mobility
- rest
-pharmacologic therapy to manage pain and prevent muscle spasms
- PT
- complementary health approaches
- surgery to remove or replace the disk
MS - correct answer- autoimmune disease that causes damage to the myelin sheath around nerves
