Week 1
SUPERFICIAL AND INTERMEDIATE BACK
Osteology: the study of the bones
Bone markings and formations appear where the ligaments, tendons, fascia connect or where arteries lay.
Back muscles attach to: occipital, temporal, spinal column, ribs, scapula, clavicle, humerus, ilium.
Vertebra: spinal process (sticks out), transverse process (to the sides), body (where rib attaches, most anterior)
12 pairs of ribs
Glenohumeral joint is where the glenoid cavity articulate with the humerus.
Costovertebral joint where head of rib articulates with vertebral body.
Intertubercular sulcus: bicipital groove- lateral lip, floor, medial lip- near head of humerus, below the greater tubercle.
Os Coxa- hip bone singular- illim, pubis, ischium. Originally separate allowing for birth and growth, but starting at 15-17 years old they begin fusing, fusion competes between 20-25.
PSIS- posterior superior iliac spine
EOP- external occipital protuberance
Superior nuchal line- same level as EOP
Inferior nuchal line- below SNL
occipital crest, runs up and down below EOP
C7, spinal process is longest, vertebra prominens
fascia is connective tissue. Superficial is fatty, deep is looks like cotton candy.
Minor over major always
5 superficial muscles of back, and all act on the upper limbs
Origin is least moveable part of muscle
Insertion is most moveable part of muscle
We will dissect EOP to median gluteal cleft
Triangle of auscultation- in 6th intercostal space. Between ribs 6 and 7
Spinal nerve leaves spine and splits in two parts.
Innervation= nerve supply
Foramen: where nerves access the skull
