the sternocleidomastoid, rectus muscle, longus muscle, and scalene muscles
Lumbrical Muscles - flexes the fingers towards the palm Flexor Digitorum Superficialis - flexes the fingers towards the palm Flexor Digitorum Profundus - flexes the tips of the fingers towards the palm Opponens Pollicis - opposes the thumb
it flexes and rotates the head
sternocleidomastoid
There would be 2 muscles involved in pulling the trigger: 1 - Flexor digitorum superficialis - flexes the proximal interphalangeal joint 2 - Flexor digitorum profundus - flexes the distal interphalangeal joint
; Sternocleidomastoid muscle - this branchiomeric muscle flexes the head (prayer muscles) when both left and right members contract. The neck twists or rotates when only one contracts. Its antagonist is the splenius capitis, a somatic muscle (which extends the head). Both these muscles act as 1st class levers.
cranial tibial muscles
The sternocleidomastoid muscles are the ones that flex when the intercostals are flexed. This will also cause the scalene muscles to flex.
The name of the muscle is sternocleidomastoid. As the name suggests, the muscle arise from the sternum and clavicle to reach the mastoid process. You have two muscles, one muscle on each side.
There are several muscles involved in flexing the hand. - Palmaris longus (flexes hand) - Flexor carpi radialis (flexes and abducts hand) - Flexor carpi ulnaris (flexes and adducts hand) - Flexor digitorum superficialis (flexes proximal and middle phalanges, flexes hand) - Flexor digitorum profundus (flexes phalanges and hand) - Flexor pollicis longus (flexes thumb and hand) - Flexor pollicis brevis (flexes thumb) There are also a few more I did not include that flex specific digits of the hand
The bicep flexes the arm at the elbow.
That's pretty vague. To name a few: Biceps Brachii- flexes and supinates the forearm, long head can also assist in flexing the humerus The largest is the Gluteus Maximus (your butt muscle)- powerful extensor of the thigh, lateral rotator of the thigh, helps steady the extended leg; extends the trunk when distal end is fixed Rectus abdominis- flexes vertebral colum, tenses anterior abdominal wall; compresses abdominal contents
scalene
