muscular System Flashcards
muscular system 2
covers, shapes and supports the skeletal tissue
contracts and moves various parts of the body
muscles1
fibrous tissues with the ability to stretch and contract according to demands of body movement
3 types of muscle tissue
skeletal/voluntary muscle contract-conscious thought
smooth/involuntary muscles - no conscious control
cardiac muscles- heart function.not conscious
how many muscles are there 2
630 (40%) of body weight
30 are facial muscles.
what muscles do we work with 1
skeletal/voluntary - attached to bones- nerves contract muscle moving bones.
3 parts of the skeletal/voluntary muscle
origin - fixed closest to skeleton, flexes but remains stationary
belly - middle
insertion - moveable attachment- farthest from skeleton
what part/direction of muscle do we massage 1
insertion to origin
Ways muscle can be positively influenced 5
massage
electrical therapy current
light rays
dry heat
moist heat
4 muscles of the scalp
frontalis - epicranius
occipitals
two temporalis
frontalis 4
biggest concern of esthetician
raises eyebrows
draws scalp forward
wrinkles forehead
epicranius 3
aka occipitofrontalis
broad muscle covering top of skull
2 parts- occipitalis and frontalis
occupitalis 2
back epicranius
muscle that draws scalp backwards
muscles of the eyebrow
corrugator
orbicularis oculi
levator palpeerde superioris muscle
corrugator2
muscle located beneath frontalis and orbicular oculi
draws eyebrow down and wrinkles forehead vertically
orbicularis oculi 2
ring muscle of eye socket
closes eye
levator palpeerde superioris muscles 2
controls eyelid
can be easily damaged during makeup application
glabella 2
corrugator and procerus
often injected with botox to stop frowning
muscles of the nose2
procerus
nasalis
procerus 2
lowers the eyebrows
causes wrinkles across bridge of nose
nasalis 3
2 part muscle
covers nose and transverse + alar parts -
flair muscle
muscles of the mouth 8
buccinator
triangularis/depressor anguli oris
mentalis
orbicularis oris
levator anguli oris
risorius
levator labii superioris / quadratus labii superioris
zygomaticus
buccinator 3
thin flat muscle of cheek
between upper and lower jaw
compresses cheeks and expels air between lips - blowing whistle
triangularis 3
aka depressor anguli oris
extends alongside chin
pulls down corners of the mouth
mentalis 2
elevates the lower lip
raises wrinkles the skin of chin
orbicularis oris 5
flat band around upper and lower lip
compresses
contracts
puckers
wrinkles lips
levator anguli oris 1
associated with smiling
risorius 1
draws corners of mouth out and back when grinning
levator labii superiorus 2
aka quadratus labii superiorus
associated with lifting wings of the nose and upper lip
zygomaticus 4
major and minor
extend from zygomatic bone to angle of mouth
elevates lips
laughing
muscles of chewing 3
massester
temporalis
coordinate to open and close mouth and bring jaw forward/backward
muscle of the ear 2
3 auricularis muscles
work together to move ear upward, forward, backwards
muscles of the neck 2
platysma
sternocleidomastoid SCM
platysma 2
broad muscle extending from the chest and shoulder muscles to the side of the chin
lowers the lower jaw and lip
sternocleidoamastoid SCM 2
extends alongside the neck from ear to collarbone
rotates head from side to side and up and down
muscles attaching arms to the body 3
lattisimus dorsi
pectorals major and minor
latissimus dosi 2
large flat triangular covering lower back
lower hipbone narrowing to rounded tendon attached to upper front of humorous
pectorals major and minor 1
muscles of chest that assist in swinging arm movements
muscles of shoulder and arm 4
trapezius
biceps
triceps
deltoids
trapezius 2
covers back of neck shoulders and upper middle region of back
shrugs shoulder and stabilizes scapula
biceps 2
produce contour of front and inner side of arm
lifts forearm, flexes elbow, turns palm outward
deltoids 2
triangular muscle covering shoulder joint
allows arm to extend outward and to side of body.
triceps 2
muscle covering entire back of upper arm
extends the forearm
muscles of the forearm 2
made up of series muscles and strong tendons
ensures good body mechanics
muscles of the hand 1
many small muscles that overlap joint to joint providing flexibility and strength
abduction 2
draws body part (finger, arm, toe) away from midline of body
separates fingers
adduction 2
draws body part (finger, toe, arm) inward toward median axis of body
draws fingers together
flexion 2
when muscles pull body part toward core of body
when biceps and arms are activated toward body
extension 2
when muscles straighten
wrist, hand and fingers form straight line
pronate 2
when forearm muscles turn inward
palms face down
supinate 2
when forearm muscles rotate outward
palms faces upward
