ABDUCTION

the action of moving a skeletal element away from the midline of the body

ACETABULUM

the socket of the hip joint; an articular surface that encompasses the head of the femur

ADDUCTION

the action of moving a skeletal element toward the midline of the body

ADOLESCENCE

considered to be between the ages of 12-24 years; the period of growth between puberty and complete fusion of the epiphysis of the long bones

ALLELE

a unit of hereditary information; an alternate form of a gene that sits at the same position on a chromosome

ALLOMETRY

the study of the relationship between the growth of an organism’s specific part(s) in relation to its entire body

ALVEOLUS

refers to tooth socket in the mandible or maxilla

AMINO ACID

chains of molecules that make up proteins. In total, there are 20 amino acids

ANALOGY

[adj. analogous] characteristics of organisms that are similar and share the same function(s), but are not the result of common ancestry

ANATOMIC POSITION

a position generally accepted as the natural stance for an organism. In bipedal hominins, the anatomic position is an upright, erect posture with the arms at the sides and the palms of the hands facing forward; in quadrupedal primates, the anatomical position is an upright, bent posture with all four limbs outstretched and palms flat on the ground

ANATOMY

the study of the structure of the body and the relationship to its parts

ANDERNACH’S OSSICLES

[syn. wormian bones] extra, small bones occuring within cranial sutures. Individual ossicles (small bone) are named for its associated suture. For example, an ossicle that is formed nearest the lambdoidal suture would be referred to as a lambdoidal ossicle

ANKYLOSIS

the fusion of two separate bony parts; an abnoram condition of a joint

ANTEMORTEM

the time period before death

ANTERIOR

a relative term used for bipedal hominins (those that travel on two legs) to describe features that are closer to the belly or front of the body; opposite of posterior. The term ventral is a synonym commonly used when referring to quadrupedal anatomy

ANTHROPOLOGY

the scientific study of humans, human culture, and the evolution of humans; subfields include archeology, cultural anthropology, linguistic anthropology, and physical anthropology

APERTURE

an opening or hole in a bone

ARCHAEOLOGY

the investigation of culture through the study of remains left by humans

ARCHAIC

ancient; old

ARTICULATED PELVIS

the right and left os coxae in proper anatomical contact with the sacrum

ARTICULATED SKULL

cranium and mandible in proper anatomical contact

ARTICULATION

the point where two or more bones are joined together. Some articulations are movable joints like the elbow or knee, while some are unmovable like the sutures between cranial bones

ARTIFACT

an object modified and/or used by hominins

ATLAS

fhe first cervical vertebrae

ATTRITION

the wearing away of a surface through grinding or friction; the gradual reduction in number or strength resulting from stress

AUDITORY MEATUS

opening in the temporal bone that is commonly referred to as the ear canal

AUTOSOME

[adj. autosomal] all chromosomes except for the sex chromosomes

AXIS

the second cervical vertebrae
