- type of cell that synthesizes the extracellular matrix and collagen
- -most common cells of connective tissue in animals
space in the bone matrix that houses the osteocyte.
type of bone cell that reabsorbs bone tissue
- -part of the growth of bones
- -haversian canals: surrounded by concentric lamellae of bone

an immovable joint-- head
- -cartilaginous thickenings on each side of notochord
- -parachordal cartilage, prechordal cartilage, olfactory capsule, optic and otic capsules.
- -enlarge- fuse--ethmoid plate and basal plate (floor of braincase).
cartilage developing around nasal cavity
- -arises from neural crest cells, not from somites
- -skeleton of pharyngeal arches
- -supports gills
- -controls shape & size of pharynx
- dorsal component of the mandibular arch, meckels cartilage.
- -palato-->quadrate bone
palatine process of premaxilla, maxilla, palatine
all-->extension, shelf small hard palate
- changes in the jaw joint
- -dentary--> squamosal jaw joint
- sound transmission
- originates from a mesenchymal stem cell
- -forms chondrocytes (cartilage cells)
- -extensive, hard, mineralized,
- -connective tissue
- -strong, resists compression, rigid
- -can be reshaped
- -highly vascularized
- -calcium phosphate--major mineral
membrane of connective tissue that snugly covers all bone
-shaft of the long bone
fibrous joint that only occurs in the skull.
prechordal and parachordal cartilages
- beneath the brain
- -develops around the olfactory and otic capsules.
separates inner ear from middle ear
- gill arches
- -comparable to gills in fish
A cartilaginous bar in the embryonic mandibular arch whose proximal end becomes ossified to form the malleus
Of or relating to a joint or joints
- bone in the middle ear
- -quadrate--> incus
the major insoluble fibrous protein in the extracellular matrix and in connective tissue
a flexible connective tissue found in many areas in the bodies of humans and other animals, including the joints between bones
microscopic canals between the lacunae of ossified bone
layer of dense irregular connective tissue that surrounds the cartilage of developing bone
involves the replacement of a cartilage model by bone
rounded end of a long bone, at its joint with adjacent bone(s) .
are united by flattened discs of fibrocartilage as found between adjacent pubic bones and between the bodies of adjacent vertebre and sernebrae.
pair of cartilaginous capsules that develop around the eyes of elasmobranch fishes and of embryos of higher vertebrates
The first branchial arch
a bone or cartilage derived from the hyomandibular arch
bundles of proteins (elastin) found in extracellular matrix of connective tissue and produced by fibroblasts and smooth muscle
cell that lies within the substance of fully formed bone. It occupies a small chamber called a lacuna
large cell responsible for the synthesis and mineralization of bone during both initial bone formation and later bone remodeling
A type of bone that ossifies directly from membrane without a cartilaginous predecessor
is the fundamental functional unit of much compact bone
An articulation or a joint between bones
Any of several types of bone articulation permitting free motion in a joint, as that of the shoulder or hip.
meshwork of interconnecting sections of a bone. It gives the spongelike appearance of a cancellous bone
greatly modified to become a single, movable, bony covering for the whole gill chamber—the operculum.
portion of the skull which develops from dermal bone. Thedermatocranial regions include the dermal bones of the cranial roof,
anatomical structure that divides the nasal cavity from the oral cavity in many vertebrates
bone of the head of higher vertebrates. It is the principal component of the cheek region in the skull, lying below the temporal series
