Question 2: bicep femoris (action, insertion, origin, antagonistic)

Answer:

Origin:long head ischial tuberosity short head line aspera & supercondylar of femur

Insertion:head femur

Actions:flexes knee, extends hip, elevates trunk, rotates tibia on femur, counteracts forward bending of hips

Antagonist:Quadriceps muscle

Question 3: tensor fasciae latae (action, antagonistic)

Answer:

action: extends knee, laterally rotates tibia, abduction and medial rotation of femur, steadies pelvis

Question 4: tibialis anterior (action, antagonistic)

Answer:

action: dorsiflexes & inverts foot, resist backward tipping

anatgonistFibularis longus, Gastrocnemius, Soleus, Plantaris, Tibialis posterior

Question 5: biceps brachii (origin, insertion, action, antagonistic)

Answer:

origin:short head: scapula. long head: supraglenoid tubercle

insertion: radial tuberosity and bicipittal aponeurosis

action:flexes elbow and supinates forearm

antagonistic: triceps brachii

Question 6: antagonist to the muscles rectus femoris, vastus medialis, vastus, intermedias, vastus lateralis

Answer:

biceps femoris, semitendonosis, sartorius

Question 7: soleus (action, antagonistic)

Answer:

action:plantar flex, steady leg on ankle while standing

antagonist: tibialis anterior

Question 8: platysma (origin, insertion, action, antagonistic)

Answer:

origin: fascia of deltoid, pectorals major

insertion: mandible, skin & tissue of lower face

action: draws lower lip angle of mouth, downward expression

Question 9: adducts the humerus?

Answer:

latissmus dorsi, pectoralis major

Question 10: external oblique (action)

Answer:

supports abdominal viscera against pull of gravity, stabilizes vertebral column during lifting, maintains posture, compresses organs, expulsion of urine, fecal, childbirth

Question 11: gluteus maximus (origin, insertion, action, antagonistic)

Answer:

origin ilium, lumbar fascia, sacrum, sacrotuberous ligament

insertion: femur, iliotibial tract

action: external rotation & extension of the hip joint, supports the extended knee, antigravity muscle in sitting antagonisti Iliacus, Psoas major, Psoas min

Question 12: internal intercostal (action, antagonistic)

Answer:

action: elevates ribs, expands thoracic cavity for inspiration, expiration depresses/retracts ribs compresses thoracic cavity, (only in forceful breathing, not relaxed) Antagonistic - external intercostals

Question 13: which muscle is antagonistic in inhalation?

Answer:

internal intercostal muscles and rectus abdominus

Question 14: sartorius (origin, action, insertion)

Answer:

origin:inferior to the anterior superior iliac spine

insertion:anteromedial surface of the upper tibia

action: Flexion, abduction, and lateral rotation of the hip, flexion of the knee

Question 15: antagonist for bicep brachii

Answer:

tricep brachii

Question 16: rectus femoris (origin, action, insertion, antagonistic)

Answer:

Origin: anterior inferior iliac spine and the exterior surface of the bony ridge, iliac portion of the acetabulum Insertion:inserts into the patellar tendon as one of the four quadriceps muscles

Actions:knee extension; hip flexion

Antagonist:Hamstring

Question 17: gastrocenemius (origin, insertion, action, antagonistic)

Answer:

origin: condyles,capsule of knee joint, lateral supercondyle of femur

insertion: calcaneus

action:plantar flex, flex knee,

antagonistic:tibialis anterior muscle

Question 18: gracilis (action, antagonistic)

Answer:

action: flexes, medially rotates tibia at knee

Question 19: orbicularis oculi (origin, insertion, action, antagonistic)

Answer:

origin: lacrimal bone, adj regions of frontal and maxilla, medial angle of eyelid

insertion: upper and lower eyelids, skin around margin of orbit

action: sphincter of eyelids

Antagonist: levator palpebrae superioris

Question 20: erector spinae (action, antagonistic)

Answer:

action:extends the vertebral column

antagonistic: rectus abdominus

Question 21: Elevates Jaw? Depresses jaw?

Answer:

masseter closes jaw, playsma opens jaw

Question 22: rectus abdominis (origin, insertion, action)

Answer:

origin: pubic sympysis

insertion:xiphoid process, costal cartilage 5-7

action:flexes lumbar region of vertebral column, forwarding bending

Question 23: diaphragm (action, synergistic)

Answer:

action:inspiration(2/3 air intake)contracts for sneezing, coughing, etc, compresses abdominal viscera in childbirth & expeulsion of feces/urine synergestic: transverse, rectus, external oblique and internal oblique, intercostals
