Chapter 3- Bone Biology and Variation Flashcards
ontogeny
development & growth
morphology
the gross shape of the bone
Types of variation
Sexual dimorphism
Population/geography
ontogeny
individual/idiosyncratic
extant
modern species
typology
the practice of choosing a single individual to represent a species
bone is composite. What is it formed of
Protein (collagen) and mineral
Wolff’s Law/Law of bone transformation
States that bone is deposited where needed and reabsorbed where not needed
joint
any connection between different skeletal elements
cartilage
tough dense connective tissue
tendons
bundles of collagen fibers that sometimes connect bones and muscles
synovial joints
such as hip, knee, elbow. Coated with slick layer of Hyaline cartilage to help them slide easily. The joint cavity is filled with synovial fluid
spheroidal/ball & socket joint
type of synovial joint that invovles round bone and concave bone
hinge joint
type of synovial joint that hinges. Elbow & knee
planar joints
type of synovial joint in which bones slide across each other (arch of foot & wrist)
cartilaginous joint
type of joint in which the bones articulate with cartilaeg between them. does not allow much movement
