Week One AIM Lectures

? and function

Scapula, Articulates with the humorous/clavical and connects the upper limb to the trunk

? and actions

Deltoid, AFE(Abducts, flexes, and extended the upper limb at the shoulder)

?

Teres Major

?, Parts, Set up, and Functions

Rotator cuff muscles, SItS(Supraspinatus, infraspinatus, tere minor, and subscapularis), Superspinatus highest, infraspinatus next, there minor next, and subscapularuis is flatter and under scapula, Stabilizes shoulder/rotates and abducts upper limb.

? and where

Anterior arm muscle, Biceps(2 head, originates from scapula and attaches to proximal end of radius)

? and where

Anterior arm muscle, Brachialis(Little bulb, lies deep in biceps, originates from humerus and attaches to ulna)

? and where

Anterior arm muscle, coracobracialis (superior to main head of bicep, thin and long)

?, where, and function

Triceps Brachii, posterior arm, extends forearm at the elbow

? and where

Pronator teres, anterior forearm

? and where

Flexor capri radialis, anterior forearm

? and where

Palmaris Longus, anterior forearm

? and where

Flexor Capri Ulnaris, Anterior forearm

? and where

Flexor Digitorium Superficialis, Anterior arm

What is the tendon?

Where the muscle attaches to bone, e.g, Flexor Digitoriem Superficialis muscle has a tendon that attaches to the radius and ulna/humerus(Looks blue in pictures, not red like rest of muscle)

? and where

Flexor Policis Longus, anterior forearm

? and where

Flexor Digitorium Profoundus, Anterior Forearm

? and where

Pronator Teres(Top) and Pronator Quadratum(Inferior), anterior forearm

? and where

Brachioradialis, posterior forearm

? and where

Anconeus, Posterior forearm

Functions and where

posterior forearm, Main function is to produce extension at the wrist and fingers

Thumb Musckles and where

Posterior, abductor polici longus on top and most lateral, extensor polices braves in middle, extensor polices longus on the bottom(Most medial)

Anatomical Position

Face Directed Forward

Arms at side

Palms of hands facing forward

Coronal Plane

Divides body into dorsal(back or posterior) and ventral(front or anterior)

Ventral

Front/Anterior

Dorsal

Back/Posterior

Adduction

Motion that pulls a structure toward the midline of the body or limb

Abduction

Motion that pulls a structure away from the mid line of the body or limb

Sagittal Plane

Divides body into right and left parts

Midsagittal

Divides the body into right and left parts through the midline

Flexion

Bending movement that decreases the angle between body parts

Extension

straightening movement that increases the angle between body parts

Transverse Plane

Divides the body into superior/cranal and inferior/caudal

Cranial

Towards head

Caudal

Towards tail

Rotations

The act of turning or twisting a body part, or the entire body, around an axis

Medial

Toward midline

Lateral

away from the midline

Anterior

Towards the front

Posterior

Towards the back

Proximal

Towards the trunk

Distal

Away from the trunk

Dorsal

Posterior hand/foot surface

Palmer

Anterior hand

Planter

Superior foot surface

Unilateral

One Side

Bilateral

Both sides

Ipsilateral

same sides

Contralateral

opposite sides

Internal/medial rotation

rotation towards midine

External/Lateral

rotation

Elevation

movement in a superior direction

Depression

movement in an inferior direction

Supination

palm anterior

pronation

palm posterior

Opposition

brings thumb and little finger together

reposition

brings thumb and little finger apart

Dorsiflextion

flex foot “up”(decrease angle between dorsal and ankle)

plantarflexion

point toes down(decrease angle between sole and back of leg)

Eversion

Sole of away from median plane(Exit sole)

Inversion

Sole of foot toward median plane (Roll ankle)

Vertebral Column Functions

(SPAM)

Support:Carry weight of body parts above pelvis

Protection:Encloses and protects the spinal cord within the spinal canal

Axis:Forms the central axis of the body

Movement:Has roles in both posture and movement

Parts of spine(5 Parts)

(CTLSC)

Cervical(7)

Thoracic(12)

Lumbar(5)

Sacrum(5, fused)

Coccyx(4, fused)

Ribs

12 total…

1-7 attached independently to the sternum

8-10 attached to the costal cartilage superior to them

11 and 12 do not have an anterior attachment and end in the abdominal musculature (Floating ribs)

Voluntary vs Involuntary Muscles

Voluntary= Consciously move

Involuntary= unconsciously move

Smooth muscle

an involuntary muscle found in the internal organs and blood vessels

Cardiac muscle

an involuntary muscle only found in the heart

Skeletal muscle

a voluntary muscle attached to the skeleton

Origin of muscle

Typically more proximal. Remains fixed during muscle contraction

Insertion of muscle

Typically more distal, moves closer to the origin during muscle contraction

?

Trapezius

?

Latissimus Dorsi

?(And Function?)

Lavator Scapulae, Elevates Scapulae

?

Rhomboid Minor
