Term
Dorsal Body Cavity
Definition
The body cavity situated near the back of the human body, and includes the cranial cavity and vertebral cavity.
Term
Mediastinum
Definition
Mediastinum - Wikipedia, the free encyclopedia
en.wikipedia.org/wiki/MediastinumThe mediastinum is an undelineated group of structures in the thorax, surrounded by loose connective tissue. It is the central compartment of the thoracic cavity.
Term
Tuberosity
Definition
A projection or protuberance, especially one at the end of a bone for the attachment of a muscle or tendon
Term
Crest
Definition
a projection, or projecting structure or ridge, especially one surmounting a bone or its border.
Term
Epicondyle
Definition
A rounded projection at the end of a bone, located on or above a condyle and usually serving as a place of attachment for ligaments and tendons.
Term
Condyle
Definition
a rounded projection on a bone, usually for articulation with another bone
Term
Process
Definition
a prominence or projection, as from a bone
Term
Meatus
Definition
Opening or Passage
Term
Fossa
Definition
a trench or channel; in anatomy, a hollow or depressed area
Term
Foramen
Definition
a natural opening or passage, especially one into or through a bone
Term
Trochanter
Definition
a broad, flat process on the femur, at the upper end of its lateral surface (greater t.), or a short conical process on the posterior border of the base of its neck
Term
Hyaline cartilage
Definition
provides sturdy support with some resilience or “give.” As easily seen in Figure 9.2, most skeletal cartilages are composed of hyaline cartilage.
Term
Elastic Cartilage
Definition
is much more flexible than hyaline cartilage, and it tolerates repeated bending better. Only the cartilages of the external ear and the epiglottis (which flops over and covers the larynx when we swallow) are elastic cartilage.
Term
Fibrocartilage
Definition
consists of rows of chondrocytes alternating with rows of thick collagen fibers. Fibrocartilage, which has great tensile strength and can withstand heavy compression, is used to construct the intervertebral discs and the cartilages within the knee joint
Term
Articular region
Definition
joints
Term
Costal region
Definition
ribs
Term
Laryngeal
Definition
near the larynx
Term
Epiphysis
Definition
End of a long bone
Term
Diaphysis
Definition
shaft, smooth surface
Term
Compact Bone
Definition
smooth and homogenous
Term
Spongy Bone
Definition
composed of small trabeculae of bone and lots of open space
Term
Central Canal
Definition
runs parallel to the long axis of the bone and carries blood vessels, nerves, and lymph vessels through the bony matrix
Term
Osteon
Definition
a central canal and all the concentric lamellae surrounding it. Haversian System
Term
Osteocyte
Definition
mature bone cells
Term
Lacunae
Definition
chambers
Term
Canaliculi
Definition
tiny canals radiating outwards from a central canal to the lacunae of the first lamella then from lamella to lamella
Term
Lamellae
Definition
thin bone layer
Term
Epiphyseal Plate
Definition
growth plate
