Study Questions #7
1. Be able to define the planes and axes of the body. Be able to define the various terms of direction.
Sagittal plane: Left and right halves (vertical place) Frontal plane: Anterior and posterior halves (lateral plane)
Transverse plane: Superior and inferior halves (horizontal plane) Medial: Near midline of body Lateral: Away from
midline of body Superior: Toward head Inferior: Toward feet Anterior: To the front Posterior: To the back Proximal:
Toward the trunk Distal: Away from the trunk Internal: Away from the skin surface External: On skin surface
2. Be able to identify and give functions for the structures learned on the knee, hip, and shoulder joint
models.
Knee joint:
- Largest and most complex joint
- Weight bearing
- Locomotion
- Location of patella and quadriceps tendon and patellar ligament provides better angle of pull and result in greater
strength of quads
Hip joint:
- Very stable compared to shoulder joint
- secure ball and socket joint: femur head fits into acetabulum of pelvic girdle
- bones larger and wider than shoulder joint bones
- strong joint capsules
- Wide range of movements but not as mobile as the shoulder joint
Shoulder joint:
- Combo of joints
- Glenohumeral joint designed for mobility, rather than stability
- a joint capsule, several muscles and ligaments maintain stability
- humerus head articulates w/ shallow glenoid fossa of scapula
- bones do not fit as snugly as those in hip joint
- Clavicle keeps arm out/away from body
3. Be able to define movements about the major joints.
Abduction: Movement away from body
Adduction: Movement towards body
Extension: Straightening of a joint to 180 degrees
Flexion: Bending a joint to an acute angle
Rotation: A circular movement around a fixed point
4. Know the classification of joints - fibrous, cartilaginous, synovial.
Fibrous joint: Fixed or immovable - Dense connective tissue (fibrous)
Cartilaginous joint: Slightly moveable - Hyaline cartilage or fibrocartilage
Synovial joint: Freely movable - 2 bones covered by cartilage and supported by joint capsule - Between cartilage is
synovial fluid to lubricate joints
5. Compare the hip and shoulder joints with respect to structure, strength and versatility of movement.
Hip joint: Deep ball and socket, designed to mostly bear weight, sacrifices ranges of motion for strength and stability
Shoulder joint: Complex joint (glenohumeral, sternoclavicular, acromioclavicular, scapulothoracic), shallow ball and
socket, designed for range of motion while still retaining control, rather than strength, common dislocation
6. Name the joint that contains the: (a) glenoid cavity and labrum, (b) cruciate ligaments and menisci, (c)
annular ligament and head of radius, (d) acetabulum and iliofemoral ligament.
a. Shoulder b. Knee joint c. Elbow joint d. Hip joint
Document Summary
Study questions #7: be able to define the planes and axes of the body. Be able to define the various terms of direction. Sagittal plane: left and right halves (vertical place) frontal plane: anterior and posterior halves (lateral plane) Transverse plane: superior and inferior halves (horizontal plane) medial: near midline of body lateral: away from midline of body superior: toward head inferior: toward feet anterior: to the front posterior: to the back proximal: Toward the trunk distal: away from the trunk internal: away from the skin surface external: on skin surface: be able to identify and give functions for the structures learned on the knee, hip, and shoulder joint models. Location of patella and quadriceps tendon and patellar ligament provides better angle of pull and result in greater strength of quads. Secure ball and socket joint: femur head fits into acetabulum of pelvic girdle. Bones larger and wider than shoulder joint bones.
