⫸ Median Plane. Answer: divides the body into right and left halves.
Also called the midsagittal plane.
⫸ Planes of the Body. Answer: ...
⫸ Coronal Plane. Answer: divides the body into front and rear
sections. Also called the frontal plane.
⫸ Frontal plane. Answer: divides the body into front and rear
sections. Also called the coronal plane.
⫸ Horizontal Plane. Answer: divides the body into a superior (or
upper) and an inferior (or lower) section. Also called the transverse
plane.
⫸ Median Plane. Answer: divides the body into right and left halves.
Also called the midsagittal plane.
,⫸ Midsagittal Plane. Answer: divides the body into right and left
halves. Also called the median plane.
⫸ Transverse Plane. Answer: divides the body into a superior (or
upper) and an inferior (or lower) section. Also called the horizontal
plane.
⫸ Direction and Location. Answer: ...
⫸ Anterior. Answer: front side of the body, also known as ventral.
⫸ Caudal. Answer: in quadrapeds, the tail end [see inferior].
⫸ Cranial. Answer: above or near the head, also known as superior.
⫸ Distal. Answer: farthest end from the trunk or head.
⫸ Dorsal. Answer: back side of the body, also known as the posterior.
⫸ Inferior. Answer: below also, toward the feet.
⫸ Infra-. Answer: prefix meaning below or under.
⫸ Lateral. Answer: away from the midline.
,⫸ Medial. Answer: toward the midline.
⫸ Posterior. Answer: back side of the body, also known as the dorsal.
⫸ Proximal. Answer: closest part nearest the trunk or head.
⫸ Superior. Answer: above or near the head, also known as cranial.
⫸ Supra-. Answer: prefix meaning above or over.
⫸ Ventral. Answer: front side of the body, also known as anterior.
⫸ Parts of the Human Skull. Answer: ...
⫸ Calvarium. Answer: includes the brain case.
⫸ Cranium. Answer: includes the face and the calvarium.
⫸ Mandible. Answer: the lower jaw.
⫸ Skull. Answer: includes both the cranium and mandible.
⫸ Bones of the Skull. Answer: ...
, ⫸ Ethmoid bone. Answer: sieve-like spongy bone located in the
anterior part of the floor of the cranium between the orbits. The
ethmoid is the principal supporting structure of the nasal cavity.
⫸ Frontal bone. Answer: forms the forehead, the roofs of the orbits,
and most of the anterior part of the cranial floor.
⫸ Inferior Nasal Conchae. Answer: one of three scroll-like bones that
project from the lateral wall of the nasal cavity. The inferior nasal
conchae articulate with the ethmoid, maxilla, lacrimal and paltine
bones and form the lower part of the lateral wall of the nasal cavity.
⫸ Lacrimal bone. Answer: a thin scalelike bone, roughly resembling
a fingernail in size and shape, at the anterior part of the medial wall of
the orbit, articulating with the frontal and ethmoidal bones and the
maxilla and inferior nasal concha. The lacrimal bone, the smallest and
most fragile bone of the face, is situated at the front part of the medial
wall of the orbit. It has two surfaces and four borders.
⫸ Mandible. Answer: the bone forming the lower jaw; the largest and
strongest bone of the face, presenting a body and a pair of rami, which
articulate with the skull at the tempromandibular joints.
⫸ Maxillae. Answer: paired bones uniting to form the upper jawbone.
The maxillae articulate with every bone of the face except the
mandible, or lower jawbone. The maxilla (plural: maxillae), also
known as the mustache bone, is a fusion of two bones along the
