Week 1 - Terminology class discussion
Transverse plane
Divides the body into upper and lower portions. (Radiologists refer to as transaxial/axial; referreed to as looking from feet to head in radioloy)
Coronal plane (section)
Also, Coronal plane results in front and back portions of body. Called Coronal because plane is parallel to coronal suture of the skull which divides body in half
Saggital plane (section)
Is any cut that is parallel to the median plane and divides the body into left and right portions.
Dorsal surface of the body
Posterior; toward the back; opposite of anterior; Dosral for bipeds; Distal.
Dorsal surface of the head
Toward the back of the head.
Ventral surface of the body
Anterior; front surface of the body
Frontal section
Coronal section; results in front/back portions of the body.
Anterior
Front surface of the body; ventral synonymous for a standing human.
Posterior
Dorsal; toward the back.
Lateral
To the side.
Medial
Toward the median plane (the one that divides the body from left to right).
Inferior
Nearer to the feet; caudal.
Superior
Farther above the ground; relative location; cranial.
Distal
Pertaining to the back of the body; away from midline.
Rostral
Toward the head.
Peripheral
Away from the central.
Superficial
Confined to/near the surface.
Deep
Closer to the axis of the body
External
Outside; generally reserved for the cavities within the body.
Prone
On the belly (refers to present position).
Supine
On the back (refers to present position).
Proximal
Toward the root or attachment point.
Flexion
Refers to bending at the joint (toward ventral surface, as in sit-ups).
Extension
Oposite of flexion; act of pulling two ends further apart.
Hyperextension
Extreme extension, dorsiflexion ((arching back at end of sit-up).
Dorsiflexion
Hyperextension; extreme extension (arching of back at end of sit-up).
Plantar
Refers to the sole of the foot.
Palmar
Refers to the palm of the hand.
Connective tissue
Purpose of is support and protection; composed of the intercellular material referred to as matrix, within which cells of connective tissue are bound; may be solid, liquid (blood) or gel-like.
Epithelial tissue
Outer layer of mucous membranes and cells constituting skin, linings of major body cavities and all “tubes” that pass into, out of and through the body.
Muscle tissue
Contractile tissue; classified as being striated (striped, “skeletal muscle” used to move skeletal structures); smooth (digestive tract and blood vessels), and cardiac (cells that are net-like in structure).
Neural tissue
Highly specialized communicative tussue consisting of neurons or nerve cells.
Origin
Proximal attachment of a muscle; point of attachment of a muscle with relatively little movement.
Insertion
A relatively mobile point of attachment of a muscle.
Tendon
Provides means of attaching muscle to bone.
Ligament
Connective tissue that binds bone to bone.
