chapter 7 Flashcards
What are the two major parts of the skeleton and how many bones are in each part
The axial skeleton - 80 bones (skull, vertebral, thoracic)
The appendicular skeleton - 126 bones (pectoral girdle, upper/lower limbs, pelvic girdle)
208 bones total
Name the five main bones that make up the skull. touch their locations.
Frontal
parietal
Occipital
left and right temporal
Name the four main sutures in the skull
Coronal
Squamous
Sagittal
Lambboid
(occipitomastoid stuture = most inferior)
What is the main word to describe the jaw
Mandibular (notch, condyle, ramus, angle, symphysis) Mandible = jaw
Forms the front of cranium
most of anterior cranial.
Superior walls of orbits
Frontal Bone
describe the parietal bones
Top and sides of cranium, 4 sutures mark the articulations (coronal, sagittal, lambdoid, squamous
Name the location and parts of the Occipital bone
Back and base of skull
Foramen magnum - opening for spinal cord
Occipital Condyle - articulates with atlas C1
superior&inferior nuchal lines - attachment for muscles
Opening for soundwaves to enter ear
External auditory meatus
What and where is the mandibular fossa
receives the condyl of mandible (jaw)
what is the Keystone bone and what does it do
The Sphenoid Bone. It articulates with all the other cranial bones
3 pairs of processes in a butterfly shape
Sella turcica - cavity on upper surface (forms protective enclosure for pituitary gland)
contains the sinus
name the bone between the orbits and nasal cavity
ethmoid bone
where is the zygomatic bone
cheek bone
Name the eight cranial bones
Frontal Parietal X2 Occipital Temporal X2 Sphenoid Ethmoid
The zygomatic process is part of what bone
Temporal
The bone containing cribriform plate
Ethmoid
Single dorsal process of vertebrae
Spinous
Anklebone that articulates with tibia, fibula and calcaneus
Tallus
How many facial bones are there
14
Name the bone that does not articulate with any others
Hyoid
Lateral bone of the forearm
Radius
The opening for spinal cord to pass through into skull
Foraman magnum
The heel bone
Calcaneus
end of clavicle that articulates with the shoulder blade
acromial
Vertebrae that articulate with the ribs
thoracic
