ASU BIO 201 - Chapter 9 - Joints Exam Questions and Answers Solved Correctly
Define "joint" - Answers a point at which parts of an artificial structure are joined
Name the term that is synonymous with joint - Answers Articulations
Define arthrology - Answers the study of joints
Define kinesiology - Answers the study of musculoskeletal movement
Explain how joints are named - Answers they are derived from the names of the bones involved
Define diarthrosis - Answers freely movable
ex: carpals, elbow, knee
Define amphiarthrosis - Answers slightly movable
ex: joints between the skull bones surrounding the brain,pubic symphysis or an intervertebral
cartilaginous joint., the elbow joint
Define synarthrosis - Answers little or no movement
ex: fibrous joints of the skull sutures and the cartilaginous manubriosternal joint
List four types of joints based on the way they adjacent bones are joined - Answers bony, fibrous,
cartilaginous, synovial joints
Explain the discrepancy between the number of bones in infants and adults - Answers the frontal and
mandibular bones in infants, cranial sutures in elderly, attachment of first rib and sternum with old age
Describe a synostosis and give examples of where they are located - Answers bony joint in the fibrous or
cartilaginous joints
List and describe the three types of fibrous joints - Answers sutures, gomphoses, syndesmoses
Examples of sutures - Answers cranial sutures
Examples of gomphoses - Answers the roots of the teeth (the pegs) fit into their sockets in the mandible
and maxilla
Examples of syndesmoses - Answers manubriosternal joint or the joints between the skull bones
surrounding the brain, in-between the radius and ulna as well as the tibia and fibula
, Recognize three types of sutures - Answers serrate, lap (squamous), plane (butt)
Examples of serrate sutures - Answers coronal, sagittal, lambdoid
Examples of lap (squamous) - Answers temporal and parietal bone, squamous suture
Examples of plane (butt) - Answers palatine processes of the maxillae, intermaxillary suture
Define interosseous membrane - Answers 2 bones are bound by longer collagenous fibers than in a
suture or gomphosis
Where are interosseous membranes are located in the body - Answers in between radius to the ulna
and the tibia to the fibula
List the two types of cartilaginous joints - Answers synchondroses and symphyses
Describe the two types of cartilaginous joints - Answers synchondroses: Connecting material is hyaline
cartilage---epiphyseal plate of a growing bone and between 1st rib and sternum
symphyses: bones are separated by a pad of cartilage-- intervertebral discs and pubic symphysis
Examples of synchondroses - Answers first sternocostal joint (where the first rib meets the manubrium)
Examples of symphyses - Answers pubic symphysis; the symphyses between the bones of the skull, most
notably the mandible
Explain the significance of synovial joints - Answers most structurally complex, most likely to have
complications
Draw and label a synovial joint - Answers
What is the function of the synovial joint - Answers absorb shock and reduce friction during movement
What is fibrocartilage? - Answers growth inward from joint capsule in a few synovial joints
Describe fibrocartilage that is associated with synovial joints - Answers articular disc, meniscus
Characterize the accessory structures of joints - Answers tendons, ligaments, tendon sheaths, bursae
Why warm-up exercises are so important? - Answers warm-up period before vigorous exercise helps
protect cartilage from undue wear and tear
Explain the effects of exercise on synovial joints - Answers exercise warms synovial fluid
Define axis of rotation - Answers the straight line through all fixed points of a rotating rigid body around
which all other points of the body move in circles
