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.
The Femoral nerve. (The motor branches innervate anterior thigh muscles - quadriceps, which flex the thigh and extend the knee.)
When you nod your head, the muscles that are primarily involved are the sternocleidomastoid and the longus colli muscles. These muscles work together to flex the neck and tilt the head forward.
There are over 50 muscles in the human head, mainly responsible for facial expressions, chewing, and neck movements. These muscles work together to allow us to speak, eat, and show emotions through facial expressions.
The primary muscles involved in torticollis are the sternocleidomastoid muscle and the trapezius muscle. These muscles are responsible for controlling the position and movement of the head and neck. Injury or spasm of these muscles can cause the characteristic head tilt and rotation seen in torticollis.
levator labii superioris ----------- There are actually several muscles named for their actions, levator scapuli is another. Others are named for their location, brachioradialis, or their length or shape, rhomboids, etc.
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
cranial tibial muscles
; 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.
The sternocleidomastoid muscles are the ones that flex when the intercostals are flexed. This will also cause the scalene muscles to flex.
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
