with Complete Solutions
Bone Correct Answer-hard, rigid, and very dense. Its cells are
continually turning over and remodeling.
Joints Correct Answer-is the place of union of two or more bones. Joints
are the functional units of the musculo-skeletal system because they
enable the mobility needed for activities of daily living (ADLs).
Non synovial joints Correct Answer-the bones are united by fibrous
tissue or cartilage and are immovable.
Synovial joints Correct Answer-are freely movable because the bones
are separated from each other and enclosed in a joint cavity: are freely
movable because the bones are separated from each other and enclosed
in a joint cavity.
Cartilage Correct Answer-avascular, receiving nourishment from
synovial fluid that circulates during joint movement.
Ligament Correct Answer-fibrous bands running directly from one bone
to another that strengthen the joint and help prevent movement in
undesirable directions.
Bursa Correct Answer-enclosed sac filled with viscous synovial fluid,
much like a joint. Bursae are located in areas of potential friction.
,Muscles Correct Answer-When they contract, they produce movement.
Muscles are of three types: (a) skeletal, (b) smooth, and (c) cardiac.
Skeletal Muscles Correct Answer-is composed of bundles of muscle
fibers (fasciculi).
Temporomandibular joint Correct Answer-the articulation of the
mandible and the temporal bone. You can feel it in the depression
anterior to the tragus of the ear. The temporomandibular joint enables
jaw function for speaking and chewing.
Vertebrae Correct Answer-33 connecting bones stacked in a vertical
column.
Glenohumeral joint Correct Answer-the articulation of the humerus with
the glenoid fossa of the scapula. Its ball-and-socket action allows great
mobility of the arm in many axes. The joint is enclosed by a group of
four powerful muscles and tendons that support and stabilize it.
Subacromial bursa Correct Answer-helps during abduction of the arm so
that the greater tubercle of the humerus moves easily under the acromion
process of the scapula.
Rotator cuff Correct Answer-The joint is enclosed by a group of four
powerful muscles and tendons that support and stabilize it
, Radiocarpal joint Correct Answer-is the articulation of the radius (on the
thumb side) and a row of carpal bones.
Midcarpal joint Correct Answer-is the articulation between two parallel
rows of carpal bones.
Hip joint Correct Answer-The hip joint is the articulation between the
acetabulum and the head of the femur.
Knee joint Correct Answer-The knee joint is the articulation of three
bones—(a) the femur, (b) the tibia, and (c) the patella (kneecap)—in one
common articular cavity.
Suprapatellar pouch Correct Answer-that extends up as much as 6 cm
behind the quadriceps muscle. Two wedge-shaped cartilages, the medial
and lateral menisci, cushion the tibia and femur.
Cruciate ligaments Correct Answer-crisscross within the knee, providing
anterior and posterior stability and helping control rotation.
Collateral ligaments Correct Answer-connect the joint at both sides,
providing medial and lateral stability and preventing dislocation.
Numerous bursae prevent friction.
Prepatellar bursa Correct Answer-lies between the patella and the skin.
