Anatomical Terms Flashcards
Anatomical position, or standard body position
The body is erect with feet slightly apart, with palms facing forward and the thumbs pointing away from the body (anteriorly); important because directional terms refer to the body as if in this position
Directional terms
Explain where one body structure is in relation to another (e.g. the ears are LATERAL to the nose)
Superior (cranial)
Toward the head end or upper part of a structure or the body; above (e.g. the head is superior to the abdomen)
Inferior (caudal)
Away from the head end or toward the lower part of a structure or the body; below (e.g. the navel is inferior to the chin)
Anterior (ventral)
Toward or at the front of the body; in front of (e.g. the breastbone is anterior to the spine)
Posterior (dorsal)
Toward or ate the back of the body; behind (e.g. the heart is poster to the breastbone)
Medial
Toward or at the middle of the body; on the inner side of (e.g. the heart is medial to the arm)
Lateral
Away from the midline of the body; on the outer side of (e.g. the arms are lateral to the chest)
Intermediate
Between a more medial and a more lateral structure (e.g.The collarbone is intermediate between the breastbone and shoulder)
Proximal
Closer to the origin of the body part or the point of attachment of a limb to the body trunk (e.g. the elbow is proximal to the wrist)
Distal
Farther from the origin of a body part or at the point of attachment of a limb to the body trunk (e.g. the knee is distal to the thigh)
Superficial (external)
Toward or at the body surface (e.g. the skin is superficial to the skeletal muscles)
Deep (internal)
Away from the body surface; more internal (e.g. the lungs are deep to the skin)
Regional terms
Used to designate specific areas within the major body divisions, includes two fundamental divisions, the axial and the appendicular parts
Axial part
Makes up the main axis of the body, includes the head, neck, and trunk
Appendicular part
Consists of the appendages, or limbs, which are attached to the body’s axis
Cephalic regions
Includes frontal, orbital, nasal, oral, mental, otic, occipital (back of head)
Cervical region
Neck area
Thoracic
Includes sternal, auxiliary, mammary
Abdominal
Includes umbilical
Pelvic
Includes inguinal (groin)
Pubic
Includes genital
Back (dorsal)
Includes scapular, vertebral, lumbar, sacral, gluteal, perineal (between anus and external genitalia)
Upper limb
Includes lacrimal, brachial (arm), antecubital, olecranal, ante brachial (forearm), carpal (wrist)
Manus (hand)
Includes metacarpal, palmar, polled, digital
Lower limb
Includes coal (hip), femoral (thigh), patellar, popliteal, crural (leg), rural (calf), fibular or peroneal
Pedal (foot)
tarsal (ankle), calcaneal, metatarsal, digital, plantar, hallux
Section, or plane
The flat surface where the body is often cut for anatomical studies
Name 4 different planes
sagittal, frontal, transverse, and oblique; the first 3 lie at right angles to each other, the last is seldom used
Sagittal planes, “arrow”
A vertical plane that divides the body into right and left parts; includes median (or midsagittal) planes and parasagittal planes
Median, or midsagittal, planes
a sagittal plane that lies exactly in the midline
Parasagittal planes
All other sagittal planes, offset from the midline
Frontal, or coronal, planes
Vertical planes that divide the body into anterior and posterior parts
Transverse, or horizontal, plane
Runs horizontally from left to right, dividing the body into superior and inferior parts; also called a “cross section”
