Lesson 5 Part 2 Might Not Be Part Flashcards
divides the nasal cavity into right and left
Nasal septum
contains the eyeball and associated structures
Orbits
openings
Foramina
immovable joint
Sutures
cavities within certain cranial and facial bones near the nasal cavity
Paranasal sinuses
areas where unossified mesenchyme develops into dense connective tissues of the skull
Fontanels
A unique bone that does not articulate with any other bone
Hyoid Bone
Supports the tongue and provides attachment for muscles and ligaments
Hyoid Bone
Spine/backbone/spinal column
33 vertebral bones in children
26 vertebral bones in adults
Cervical (7)
Thoracic (12)
Lumbar (5)
Sacrum
Coccyx
Vertebral Column
Vertebral body
Vertebral arch
Processes
Spinous process
Transverse process (2)
Superior articular process (2)
Inferior articular process (2)
The Typical Vertebra
Movement of relatively flat bone surfaces back-and-forth and side-to-side over one another; little change in angle between bones.
Gliding
Increase or decrease in angle between bones.
Angular
Decrease in angle between articulating bones, usually in sagittal plane.
Flexion
Movement of trunk in frontal plane.
Lateral flexion
Increase in angle between articulating bones, usually in sagittal plane.
Extension
Extension beyond anatomical position.
Hyperextension
Movement of bone away from midline, usually in frontal plane.
Abduction
Movement of bone toward midline, usually in frontal plane.
Adduction
Flexion, abduction, extension, adduction, and rotation in succession (or in the opposite order); distal end of body part moves in circle.
Circumduction
Movement of bone around longitudinal axis; in limbs, may be medial (toward midline) or lateral (away from midline).
Rotation
Occurs at specific joints.
Special
Superior movement of body part.
Elevation
Inferior movement of body part.
Depression
Anterior movement of body part in transverse plane.
Protraction
