Unit 1- Introduction To Anatomy Flashcards
Anatomy
(To cut apart) many body parts are easier to study when they are cut from the body
Terminologia Anatomica (TA)
A list of proper (official) anatomical names to combat the confusion
Normal anatomic position
The body is standing erect with the head and feet directly forward
Sagittal plane [planum sagittalis]
Any vertically oriented plane that divides the body into right and left portions
Median plane [planum medianus]
Sagittal plane that courses through the anterior (front) and posterior (back) midlines of the body
Frontal (coronal) plane [planum frontalis/ coronalis ]
Any vertically oriented plane perpendicular to the median plane which divides the body Into anterior (front) and posterior (back) portions
Medial [medialis]
Toward or relatively closer to the median plane
Lateral [lateralis]
Away from or relatively farther from the median plane
Posterior [posterior]
Toward or relatively closer to the backside of the body
Anterior [anterior]
Toward or relatively closer to the front side of the body
Superior [superior]
Toward or relatively closer to the top of the head
Inferior [inferior]
Away from or relatively farther from the top of the of the head
Proximal [proximalis]
Toward or relatively closer to a reference point.
Distal [distalis]
Away from or relatively farther from a reference point
Transverse plane [ planum transversus]
Any horizontally oriented plane that divides the head, neck, trunk or limbs into the superior (upper) and inferior (lower) portions
Superficial/ external [superficiallis, externus]
Near or relatively closer to the outer aspect (surface) of the body or part.
Deep, Internal [profundus, internus]
Near or relatively closer to the central aspects of the body or part
Dorsal [dorsalis]
Toward or relatively close to the back
Ventral [ventralis]
Toward or relatively closer to the “belly”
Palmar/ volar [palmaris/ volaris]
Toward or relatively closer to the anterior aspect of the hand (The side where the palm is located)
Plantar [plantaris]
Toward or relatively closer to the sole (Underside) of foot were is synonymous with inferior
Middle [medius]
A position between superior/ inferior, anterior/Posterior, space proximal/distal or superficial/deep
Intermediate [ intermedius]
A “ side to side” position between medial and lateral structures
Radial [radialis]
Radial implies toward or relatively closer to the lateral aspect of the entire superior limb
Ulnar [ulnaris]
Ulnar implies toward or relatively closer to the medial aspect of the entire superior limb
Tibial [tibialis]
Tibial Implies toward or relatively closer to the medial side of the inferior limb
Fibular/ peroneal [fibularis/ peronealis]
Fibular implies toward or relatively closer to the lateral aspect of the inferior Limb
Longitudinal [longitudinalis]
Parallel to the long axis of an elongated structure (lengthwise)
Transverse [transversus]
Perpendicular to the long axis of an elongated structure (across)
Ipsilateral
Indicates a structure or position on the same side of the body
Contralateral
Contralateral implies Opposition on the opposite side of the body
Right [dexter]
On the right hand side of the body
Left [sinister]
On the left side of the body
Central [centralis]
Towards the center
Peripheral [peripheralis]
Away from the center
Vertical [verticalis]
Within a sagittal or frontal plane
Horizontal [horizontalis]
Within a transverse plane
Caput
(Head) The superior extremity of the body that is supported by the neck. it is subdivided by the cranium and ..
Cranium
(Cranium) The portion of the head that surrounds and houses the brain (braincase)
Cubitus
(Elbow) The portion of the superior limb at the junction of the brachium and the antebrachium
Antebrachium
(Forearm) The portion of the superior limb between the elbow and the wrist “the lower arm”
Manus
(Hand) The distal portion of the superior limb beyond the forearm. It is subdivided into wrist, metacarpus and digits
