shoulder (rotator cuff muscle)• Stretch:

Deltoid Muscle By: Hannah Thomas

Origin: Clavicle and Scapula (Acromion and Adjacent Scapular Spine)

Insertion: Deltoid Tuberosity of Humerous

Primary Actions: Abduction at Shoulder

Stretches: Arm cross, shoulder roll

Delta = Triangle, so it is triangular shaped

Pectoralis Major

Hillary Pyatt

“pectoralis major”- large pectoral muscleOrigin- cartilege of ribs 2-6, body of sternum and clavicle. Insertion- greater tubercle of humorousAction- flexion, adduction, and medial rotation at shoulder.Exercise- pushup

Levator Scapulae• Levator means to lift – lifts the

scapula• Origin: Transverse Process of

first 4 cervical vertebrae • Insertion: Vertebral border of

scapula• Primary action: Elevate

scapula• Stretch: Sit with feet flat on

the floor, relax shoulders, bring chin back towards shoulders, eyes look straight ahead

Tensor Fasciae Latae• Tensor=to stretch; Fascia=band; Latae=side• Origin: Iliac crest• Insertion: Iliotibial tract• Action: Flexion, abduction, and medial

rotation at hip

Adductors

• An athlete pulls one of these muscles when strains his/her groin– Adductor brevis– Adductor longus– Adductor magnus– Pectineus– Gracilis

ADDUCTORS ORGIN INSERTION ACTION

Adductor Brevis: Inferior ramus of the pubis

Linea aspera of pubis

Adduction, flexion, and medial rotation at hip

Adductor Longus: Inferior ramus of pubis posterior to adductor brevis

Linea aspera of pubis

Adduction, flexion, and medial rotation at hip

Adductor Magnus Inferior ramus of pubis posterior to adductor brevis

Linea aspera of pubis

Adduction at hip joint; superior portion produces flexion, inferior portion produces extension

Pectineus Superior ramus of pubis

Inferior to lesser trochanter of femur

Adduction, flexion, medial rotation at hip joint

Gracillis Inferior ramus at pubis

Medial surface of tibia inferior to medial condyle

Flexion at knee; adduction and medial rotation at hip

Transverse Abdominis Mackenzie Gordon • Name: ‘Transverse’ refers to going across• ‘Vacuum’ excerciseShape: Resembles the Big Dipper on its sideLocation: Deepest of the abdominals, lateral to the rectus abdominisOrigin: Lateral inguinal ligament, iliac crest, thoracolumbar fascia, cartilage of lower 6 ribsInsertion: Abdominal aponeurosis to linea albaPrimary Actions: Compresses abdominal contents, assists respiration

Rectus Abdominis • Name: ‘Rectus’ means strait• Back bendShape: ‘Six pack’, vertical strip Location: Superficial, medial to the external obliqueOrigin: Pubic crest and pubic symphysis Insertion:Cartilage of 5th, 6th, 7th ribs, and xiphoid process Primary Actions: Flexes the vertebral column (allows you to stand up strait)

Vastus Intermedius

• Origin- anterior and lateral surface of femur along linea aspera

• Insertion- tibial tuberosity by way of patellar ligament

• Primary actions- extension at knee

• Exercise- quad stretch

Vastus Lateralis

• Origin- anterior and inferior to greater trocanter of femur and along linea aspera

• Insertion- tibial tuberosity by way of patellar ligament

• Primary actions- extension at knee

• Exercise- quad stretch

Vastus Medalis

• Origin- entire length of linea aspera of femur

• Insertion- tibial tuberosity by way of patellar ligament

• Primary actions- extension at knee

• Exercise- quad stretch

Sartorius-Latin root-Sartor (meaning tailor)-reference to the cross legged position

in which tailors sit.

Origin-Anterior superior spine of illeum.

Insertion-Medial surface of tibia, near tibial tuberocity.

Action-Flexion at knee; flexion and lateral rotation at hip.

Stretch/Exercise- Climbing stairs

Supraspinatus( above the spine)

• Origin: supraspinous fossa of the scapula• Insertion: greater tubercle of the humerus • Primary actions: abduction of the arm at the

shoulder (assists deltoid)

Infraspinatus (below the spine)

• Origin: infraspinous fossa of the scapula• Insertion: same as above • Primary actions: extension, horizontal (transverse)

extension and lateral rotation of humerus at the shoulder joint

• Origin– Spinous processes of the lower thoracic

vertebrae, ribs, and lumbar vertebrae• Insertion

– Intertubercular groove of humerus• Primary Actions

– Extension, adduction, and medial rotation at shoulders

The name derives from the Greek word "spléníon," which means bandage. Capitis means of the head, and cervicis means of

the neck.

Splenius Capitis, Cervicis

Origin Spinous processes of lower cervical( 7th) and upper T3 or T4.

Insertion Inserts under the Sternocleidomastoideus, into the mastoid process and into the occipital bone and between the upper

cervical vertebrae.

ActionExtends and rotates cervical spine The splenius muscle is a

prime mover for head extension.

Stretchlateral flexion and rotation of the neck and hyper extending

the neck.

Splenius Capitis

ORIGINSpinous processes and supraspinous ligaments of T3-

6.

InsertionPosterior tubercles of transverse processes of C1-3.

ACTIONExtends and rotates cervical spine

Stretch lateral flexion and rotation of the neck and hyper

extending the neck.

Internal and External Obliques• Internal obliques are under external

ones• External: Origin—lower 8 ribs

• Insertion—linea alba and iliac crest• Action—compresses abdomen, depresses

ribs, flexes or laterally flexes vertebral column

• Internal: Origin—Iliac crest, and adjacent connective tissues• Insertion—lower ribs, xiphoid of sternum

and linea alba• Action—same as external
