Head, face, and neck musclature Flashcards
parts of the skull
- frontal
- temporal: mastoid process
- parietal
- occipital
- mandible
- zygomatic
- ramus (ramus, body, condylar process)
clavicle and where it attaches
- connects to scapula at the acromial end
- connects to sternum at the sternal end
parts of the scapula
- coracoid process
- acromion
- lateral/medial border
- superior/inferior angle
- scapula spine
- glenoid cavity
skull joints (type and movement)
type: suture (solid)
movement: none
- coronal suture
- sagittal suture
- lambdoid suture
temporomandibular joint
type: condylar
movement: elevation/depression, protraction/retraction, lateral deviation
atlanto -occipital joint
type: condylar/ellipsoid
movement: flexion, depression, side flexion (left and right)
atlantoaxial joint
type: pivot
movement: rotation
- CI and CII
intervertebral joint
type: solid
movement: minimal to none
ligaments: intervertebral disc
roles of the intervertebral discs and what its made of
- absorbs shock, binds spinal column together, supports body weight
- composed of fibrocartilage rings
facet joints
type: plane
movement: sliding/gliding
types of breathing mechanics
- inspiration
- expiration
inspiration
- skeletal muscles move rib cage up and ut to allow for lung expansion
- ribs move in a bucket handle motion
- the diaphragm increases thoracic volume by compressing abdominal viscera, allowing for increased lung expansion
what are the muscles used in inspiration
many muscles act as a synergist or fixators
- diaphragm
- intercostals
- scalenes (scalene mass)
what are the joints used in inspiration
- costotransverse joints
- costovertebral joints
- sternocostal joints
expiration
- skeletal muscles move rib cage down and in during forceful exhalation to force air out of the lungs
- the ribs move in a bucket handle motion
- the diaphragm passively moves up, back into its resting position
