Study Guide 9

• -lie in lacunae
• -fluid-filled spaces within the matrix
• -can divide
• -daughter cells grow further apart as they secrete extra cellular material

• 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
• -central haversian canal contains nerve, blood vessels

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

all-->extension, shelf small hard palate

• changes in the jaw joint
• -dentary--> squamosal jaw joint

• sound transmission
• -articular-->malleus

• 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.

• 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

forms the incus

sound transmission

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
