chapter 14: joints and muscles

Question 1

cartilage

Answer 1

firm connective tissue primarily found in joints. articular cartilage covers the contacting surfaces of bones

Question 2

Joint

Answer 2

junction of two or more bones, which often allows for movement of these bones (also called articulation)

Question 3

intervertebral disk

Answer 3

cartilaginous pad found between the vertebrae in the spine

Question 4

meniscus

Answer 4

crescent-shaped cailage found in some joints, including the knee

Question 5

pubic symphysis

Answer 5

cartilaginous joint at which two pubic bones come together anteriorly at the midline

Question 6

synovia

Answer 6

fluid secreted by the synovial membrane and found in joint cavities, bursae, and around tendons

Question 7

bursa

Answer 7

fluid-filled sac that allows for easy movement of one part of a joint over another

Question 8

ligament

Answer 8

flexible, tough band of fibrous connective tissue that attaches one bone to another at a joint

Question 9

tendon

Answer 9

band of fibrous connective tissue that attaches muscle to bone

Question 10

aponeurosis

Answer 10

strong sheet of tissue that act as a tendon to attach muscles to bone

Question 11

muscle

Answer 11

tissue composed of specialized cells with the ability to contract to produce movement; the three types of muscle tissue are skeletal, smooth, and cardiac

Question 12

fascia

Answer 12

band or sheet of connective tissue that encloses muscles and separates their layers

Question 13

skeletal muscles

Answer 13

attached to bones by tendons and make body movement possible. Skeletal muscles produce action by pulling and by working in pairs. They are also known as voluntary muscles because we have control over these muscles. alternating dark and light bands create striations (stripes). (also called striated muscles)

Question 14

cardiac muscle

Answer 14

forms most of the wall of the heart. its involuntary contraction produces heartbeat (also called myocardium)
