body planes
- correct answer imaginary lines used for reference; they include the median plane, the coronal plane,
and the transverse plane.
Median Plane
- correct answer divides the body into right and left halves. Also called the midsagittal plane.
Planes of the Body
- correct answer ...
Coronal Plane
- correct answer divides the body into front and rear sections. Also called the frontal plane.
Frontal plane
- correct answer divides the body into front and rear sections. Also called the coronal plane.
Horizontal Plane
- correct answer divides the body into a superior (or upper) and an inferior (or lower) section. Also called
the transverse plane.
Median Plane
- correct answer divides the body into right and left halves. Also called the midsagittal plane.
Midsagittal Plane
- correct answer divides the body into right and left halves. Also called the median plane.
,Transverse Plane
- correct answer divides the body into a superior (or upper) and an inferior (or lower) section. Also called
the horizontal plane.
Direction and Location
- correct answer ...
Anterior
- correct answer front side of the body, also known as ventral.
Caudal
- correct answer in quadrapeds, the tail end [see inferior].
Cranial
- correct answer above or near the head, also known as superior.
Distal
- correct answer farthest end from the trunk or head.
Dorsal
- correct answer back side of the body, also known as the posterior.
Inferior
- correct answer below also, toward the feet.
Infra-
- correct answer prefix meaning below or under.
Lateral
- correct answer away from the midline.
Medial
- correct answer toward the midline.
,Posterior
- correct answer back side of the body, also known as the dorsal.
Proximal
- correct answer closest part nearest the trunk or head.
Superior
- correct answer above or near the head, also known as cranial.
Supra-
- correct answer prefix meaning above or over.
Ventral
- correct answer front side of the body, also known as anterior.
Parts of the Human Skull
- correct answer ...
Calvarium
- correct answer includes the brain case.
Cranium
- correct answer includes the face and the calvarium.
Mandible
- correct answer the lower jaw.
Skull
- correct answer includes both the cranium and mandible.
Bones of the Skull
- correct answer ...
, Ethmoid bone
- correct 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
- correct answer forms the forehead, the roofs of the orbits, and most of the anterior part of the cranial
floor.
Inferior Nasal Conchae
- correct 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
- correct 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
- correct 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
- correct 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 palatal fissure that form the upper jaw. This is
similar to the mandible (lower jaw), which is also a fusion of two halves at the mental symphysis.
Sometimes (e.g. in bony fish), the maxilla is sometimes called "upper maxilla", with the mandible being
the "lower maxilla". Conversely, in birds the upper jaw is often called "upper mandible".
Nasal bone
- correct answer small oblong bones that meet at the middle and superior part of the face. Their fusion
forms the superior part of the bridge of the nose.
