Definition
The bones of the fingers and of the toes
Phalanges
Define
Analogy
similar in appearance or function but otherwise different
Definition
a thin fibrous cartilage between the surfaces of some joints
Menisci
Definition
the enclosing structure formed by the pelvis, providing attachment for the hind limbs
Pelvic girdle
Definition
a very porous type of bone found in animals. It is highly vascularized and contains red bone marrow. This bone is usually located at the ends of the long bones (the epiphyses), with the harder compact bone surrounding it
Spongy bone
What shape classification is given to this bone?

Sesamoid bone
What is a joint/articulation?
Areas where two or more adjacent bones interact
Definition
Part of the top portion of the skull which protects the brain. The bones of the cranium include the frontal, parietal, occipital, temporal, sphenoid, and ethmoid bones
Cranial bones
Define
Compact bone
dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces (lacunae) that contain the osteocytes, or bone cells
True or False:
Cartilage is well vascularised
False
Define
Anatomy
the branch of science concerned with the bodily structure of humans, animals, and other living organisms, especially as revealed by dissection and the separation of parts
Define
Hyaline cartilage
the glass-like but translucent cartilage found on many joint surfaces
Define
Ulna
the thinner and longer of the two bones in the human forearm, on the side opposite to the thumb
Definition
The definition of a homologous structure is an organ or body part that appears in different animals and is similar in structure and location, but doesn’t necessarily share the same purpose
Homologous structures
Which bones are considered as part of the hip?
Pelvis
Proximal femur
Define
Thorax
the part of the body of a mammal between the neck and the abdomen, including the cavity enclosed by the ribs, breastbone, and dorsal vertebrae, and containing the chief organs of circulation and respiration; the chest
What connective tissue connects bone to bone?
Ligaments
Definition
A type of articulation between bony surfaces that permits limited motion and is connected by ligaments or elastic cartilage, such as that between the vertebrae
Amphiarthrosis
Define
Metacarpals
any of the five bones of the hand
Which bones are considered as part of the shoulder?
Scapula
Clavicle
Humerus (head of)
Define
Pectorial girdle
the skeletal framework which provides attachment for the forelimbs or pectoral fins, usually consisting of the scapulas and clavicles
Define
Mandible
the jaw or a jawbone, especially the lower jawbone in mammals and fishes
Definition
a triangular bone in the lower back formed from fused vertebrae and situated between the two hipbones of the pelvis
Sacrum
Definition
a thick flat triangular movable bone that forms the anterior point of the knee and protects the front of the joint
Patella
