Skeletal System Axial Skeleton Pt 1 Lab10
How many named bones are there in the human body?
206
How many bones are ther in the axial skeletal system?
80
Which of the two divisions consists of the bones that lie in the longitudinal axis of the human body?
appendicular
What are the two main divisions of the skeletal system
axial and appendicular
atlas articulates superiorly with this bone
axis
articulation between the mandible and skull
condylar process
rounded bump usually fits into a fossa on another bone to form a joint
condyle
suture between the frontal bone and the parietal bone
coronal
moderately raised ridge, generally a site for muscle attachment
crest
flat surface that forms a joint with another facet or flat bone
facet
long, cracklike hole for blood vessels and nerves
fissure
round hole for vessels and nerves
foramen
depression, often receives an articulating bone
fossa
8 bones that make up the cranium
frontal - 1 parietal - 2 temporal - 2 ethmoid - 1 sphenoid - 1 occipial - 1
distinct epiphysis on a long bone, separated from the shaft by a narrowed portion (or neck)
head
facial bone that contains paranasal sinus
inferior nasal conchae, frontal, shpenoid, ethmoid, paire maxillary
function of sutures
join bones
tear ducts that pass through these paired bones
lacrimal
suture between the parietal bones and the occiput
lambdoid
similar to a crest but not raised as much
line
chin bone
mandible
lower jaw bone
mandible
only freely movable skull bone
mandible
upper jaw bone
maxillae
contains teeth sockets
maxillae, alveolar process
tubelike opening or channel
meatus
smaller bone of the hard palate
palatine
suture between the two parietal bones
sagittal
bone marking that protects the pituitary gland
sphenoid, sella turcica
similar to crest but raised more, sharp pointed process for muscle attachment
spine or spinous process
groove or elongated depression
sulcus
immovabe joints between skull bones
suture
middle and inner ear are found within this bone
temporal
a small tuberosity
tubercle
inferior hone of the nasal septum
vomer
facial bones
vomer - 1 maxillae -2 zygomatic - 2 palatine -2 lacrimal -2 nasal -2 inferior nasal conchae -2 mandible -1
cheek bones
zygomatic
How many bones are there in the appendicular skeleton
126
