Skeletal and Muscular System (IRREGULAR BONES (Irregular bones of the…

- - - - Frontalis Muscle: muscle of the forehead; elevates eyebrow, wrinkles skin of forehead
      - Coronal suture; supraorbial foramen, frontal sinus
    - - Temporalis Muscle: Fan-shaped muscle on side of cranium; main action to elevate an retract mandible
        
        Squamous; encircled by squamous suture, zygomatic process, mandibular fossa. Tympanic; external auditory meatus, styloid process. Mastoid; mastoid process, mastoid notch, mastoid foramen, stylomastoid foramen.
        
        Masseter muscle; shorter and superficial to the temporalis, synergist in elevating mandible, some protraction and excursion.
    - - sagittal, coronal, lambdoid, squamous sutures
    - - Support cartilages that shape lower portion of the nose.
    - - Lacrimal fossa; form part of medial wall of each orbit.
    - - Inferior half of the nasal septum
  - - - 12; ends attach to the vertebral column posterior, most anterior ends attach to the sternum
        
        2-10; Angle: lateral curve of the rib; Shaft: long, gentle sloping, blade-like portion of rib.
        Tubercle, Neck, Head, Articular facet- for transverse process, superior and inferior articular facets for vertebral bodies.
        Costal groove, shaft.
      - Teres Major muscle helps rotate upper arm; Serratus anterior- located inside the ribs, keeps the shoulder blade against the chest wall.
      - STERNUM
        
        Manubrium; broad superior portion, clavicular notches.
        Body; longest part of the sternum, sternal angle
        Xiphoid; interior point of sternum.
        
        Muscles attached via tendons to the manubrium; sternocleidomastoid, pectoralis major, sternohyoid, and sternothyriod muscles.
      - True ribs, false ribs, floating ribs.
- - - - Tibia; thick, medial and lateral condyles, tibial tuberosity, medial malleolus.
        semimembranosus muscle, popliteus muscle, tibialis anterir muscle and extensor digitorum longus muscle.
        Fibula; slender, lateral strut that helps stabilize ankle, head, lateral malleolus, joined to tibia by interosseous membrane
        fibularis brevis, soleus muscle, tibialis posterior muscle, flexor hallucis longus muscle.
- - - - Zygomatic major muscle,zygomatic minor muscle, Buccal.
  - - - (Irregular Flat) Scapula- triangular plate that posteriorly overlies ribs 2 to 7, suprascapular notch; spine- supraspinous fossa, infraspinous fossa.
        
        Biceps brachii- short and long head, coracobrachialis, deltoid, infraspinatous, latissimus dorsi, levator scapulae, omohyoid, pectoralis minor.
  - - - Iliopsoas muscle- flexes hip, attaches to the upper thigh bone.
        Rectus femoris muscle, front of thigh.
- - - - phalanges 1-5; head, body, base
        flexor digitorm superficialis, flexor digitorum profundus, flexor pollicis longus.
        
        metacarpals body, base 1-5
  - - - tarsals; calcaneus, talus, cuboid, navicular, cuneiforms- lateral, mediial, and middle.
        gastrocnemius, soleus, peroneus longus, peroneus brevis, tibialis posterior, flexor hallucis longus, and flexor digitorum longus muscles- plantar flexion on the foot and ankle.
