Teres Major • Meaning: teres- long and rounded shape • Origin: lateral border of scapula • Insertion: greater tubercle of humerus • Action: lateral rotation at shoulder • Stretch:
Teres Minor • Meaning: same as teres major • Origin: inferior angle of scapula • Insertion: intertubercular groove of the humerus • Action: adduction and medial rotation at the shoulder (rotator cuff muscle) • Stretch:
Deltoid Muscle By: Hannah Thomas Delta = Triangle, so it is triangular shaped Origin: Clavicle and Scapula (Acromion and Adjacent Scapular Spine) Insertion: Deltoid Tuberosity of Humerous Primary Actions: Abduction at Shoulder Stretches: Arm cross, shoulder roll
Pectoralis Major Hillary Pyatt
“pectoralis major”- large pectoral muscle Origin- cartilege of ribs 2-6, body of sternum and clavicle. Insertion- greater tubercle of humorous Action- 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
Transverse Abdominis Mackenzie Gordon • Name: ‘Transverse’ refers to going across • ‘Vacuum’ excercise • Shape: Resembles the Big Dipper on its side • Location: Deepest of the abdominals, lateral to the rectus abdominis • Origin: Lateral inguinal ligament, iliac crest, thoracolumbar fascia, cartilage of lower 6 ribs • Insertion: Abdominal aponeurosis to linea alba • Primary Actions: Compresses abdominal contents, assists respiration Rectus Abdominis • Name: ‘Rectus’ means strait • Back bend • Shape: ‘Six pack’, vertical strip • Location: Superficial, medial to the external oblique • Origin: 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 lineaaspera • Insertion-tibialtuberosity by way of patellar ligament • Primary actions- extension at knee • Exercise- quad stretch
Vastus Medalis • Origin- entire length of lineaaspera of femur • Insertion-tibialtuberosity 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
Splenius Capitis 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. Action Extends and rotates cervical spine The splenius muscle is a prime mover for head extension. Stretch lateral flexion and rotation of the neck and hyper extending the neck.
ORIGIN Spinous processes and supraspinous ligaments of T3-6. Insertion Posterior tubercles of transverse processes of C1-3. ACTION Extends 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, xiphoidof sternum and linea alba • Action—same as external
