skeletal muscles consist of bundles of muscles cells, each wrapped in their connective tissue sheath.
Gluteus maximus The hip muscle commonly called the buttocks
Endomysium A muscle fiber is surrounded by this
oribicularis oculi If someone starts winking a you, their using their.
Lag phase The time between contracts in the legs
Relaxion The time during which the muscles relax in a period
Fast Twitch This causes muscle fibers to fatigue quickly
Slow Twitch Muscle fibers that are resistant to fatigue
Interior/Exterior Types of tongue muscles
Orbicularis Oculi Closes the eyelids
Origin The most stationary end of the muscle
Capitonfrontalis Raises the eyebrows
Zygotmaticus This muscle is used for smiling
Cardiac Muscle is under involuntary control
Muscle Twitch Is a contraction of an entire muscle in response to a stimulus.
Tetany The condition where muscles remains contracted without relaxing
Aerobic Respiration Occurs in the presence of oxygen
Muscle Myofibrils Contains actin and myosin, and extend from one end of the muscle fiber to the other.
Contractility The ability of skeletal muscle to shorten with force
Excitability The capacity of skeletal muscle to respond to a stimulus.
Extensibility The ability to be streched
Elasticity Ability to recoil to the original resting length.
Fascia It surrounds and separates muscles.
Motor Neurons Are nerve cells that carry action potentials to skeletal muscle fibers.
Erector spinae group of muscles on each side of the back
External intercostals elevate the ribs during inspiration.
linea alba consists of white connective tissue rather than muscle
Tendinous inscriptions cross the rectus abdominis at three or more locations, causing the abdominal wall of a well-muscled person to appear segmented.
Trapezius rotates scapula
Serratus anterior pulls scapula anteriorly
pectoralis major and latissimus dorsi muscles. The arm is attached to the thorax by the
Pectoralis major adducts and flexes the arm
Latissimus dorsi “Swimmer muscles”
Deltoid attaches the humerus to the scapula and clavicle, and is the major abductor of the upper limb.
Triceps brachii extends the forearm. Occupies the posterior compartment of the arm.
Biceps brachii flexes the forearm. Occupies the anterior compartment of the arm.
Brachialis flexes forearm
Brachioradialis flexes and supinates the forearm.
Retinaculum strong band of fibrous connective tissue that covers the flexor and extensor tendons and holds them in place around the wrist
Flexor carpi flexes the wrist
Extensor carpi extends the wrist
Flexor digitorum flexes the fingers.
Extensor digitorum extends the fingers.
intrinsic hand muscles 19 hand muscles
Interossi located between the metacarpals, are responsible for abduction and adduction of the fingers.
Quadriceps femoris extends the leg; anterior thigh muscles
Sartorius tailors muscle”; flexes the thigh
Hamstring muscles posterior thigh muscles; flexes the leg and extends the thigh.
Gastrocnemius and soleus form the calf muscle
peroneus muscles The lateral muscles of the leg
intrinsic foot 20 muscles located within the foot
occipitofrontalis It consists of two parts or bellies: The occipital belly, near the occipital bone, and the frontal belly, near the frontal bone
Smooth muscle "involuntary muscle"
Skeletal muscle "voluntary muscle"
actin and myosin. The filaments in a sarcomere are composed of
depressor supercilii Depression of eyebrow _
corrugator supercilii wrinkles forehead
iris sphincter constricts pupil
auriculares Wiggle ears
procerus Draws down the medial angle of the eyebrow giving expressions of frowning
dilator naris Dilation of nostrils
levator anguli oris smile (elevates angle of mouth)
depressor anguli oris depresses angle of mouth
sternocleidomastoid Acting alone, tilts head to its own side and rotates it so the face is turned towards the opposite side. Acting together, flexes the neck, raises the sternum and assists in forced inspiration.
scalene cervical nerves
erector spinae extends the vertebral column
levatores costarum Assists in elevation of the thoracic rib cage
external oblique Rotates torso
internal oblique Compresses abdomen and rotates vertebral column.
coracobrachialis flexes & adducts humerus
extensor digitorum extension of hand and fingers
extensor digiti minimi extends the little finger at all joints
extensor carpi ulnaris extends and adducts the wrist
flexor pollicis brevis Flexion of thumb
abductor pollicis brevis Abduction of thumb
flexor digitorum longus Primary action is Flex digits
