KINE 426 biomechanics movements, planes, axes, and linear kinematics

quiz 1 and exam 1

sagittal joint movement: extension of leg at knee joint

muscles: vastus lateralis, vastus intermedius, vastus medialis, rectus femoris (QUADS)

sagittal movement: flexion of leg at knee joint

muscles: biceps femoris, semimembranosus, semitendinosus (HAMSTRINGS)

sagittal movement: extension of thigh at hip joint

muscleS: iliopsoas, rectus femoris, sartorious, pectineus

sagittal movement: extension of thigh at hip joint

muscles: gluteus maximus, biceps femoris, semimembranosus, semitendinosus

sagittal movement: anterior tilt of pelvis at hip and lumbosacral joint

muscle: iliopsoas, rectus femoris, erector supinae, quadratus lumborum

sagittal movement: posterior tilt of pelvis at hip and lumbosacral joint

muslced: rectus abdominis, gluteus maxmimus, hamstrings

sagittal movemnts: dorsiflexion of feet at ankle joint AND plantarflexion of feet at the ankle joints

muscles at dorsiflexion: tibialis anterior

muscles at plantarflexion: medial and lateral gastrocnemius and soleus

frontal movements: adduction of the thighs at hip joint

muscles: adductor longus, adductor brevis, adductor magnus, gracilis

frontal movemnt: abduction of thigh art hip joint

muscles: tensor fascia latae, gluteus maximus, gluteus minimus

frontal movement: right lateral tilt of pelvis at hip joint

muscles: quadratus lumborum, gluteus medius, gluteus minimus, adductors (3)

frontal movement: left lateral flexion of trunk at the spinal joint

msucles: quadratus lumborum, external obliques, internal obliques, and erector spinae

transverse movements: horizontal abduction of arms at shoulder joints and horizontal adduction of arms at shoulder joint

horizontal abduction: posterior deltoids

horizontal adduction: pectoralis major

transverse movement: lateral rotation of arm at shoulder joint

muscles: infraspinatues, teres minor

transverse movement: medial rotation of arm at shoulder joint

muscles: subscapularis, pectoralis major, latissimus dorsi, teres major, anterior deltoid

transverse movement: right rotation of trunk at spinal joints

muscles: internal and external obliques

planes and axis

sagittal plane- mediolateral axis

frontal plane- anterioposterior axis

transverse plane- superioinferior axis

“rotation in the sagittal plane takes placea round the mediolateral axis”
