HESI A2 Anatomy and Physiology Exam Questions
and answers
Anatomical Position - ✅✅Provides a baseline reference point for areas of the body.
In this position the body is: Erect, The feet are slightly apart, the head held high, the arms are at the
sides, and the palms are facing forward.
Body Planes - ✅✅Plans are imaginary flat plates. A section is a real or virtual cut made along a plane.
Sagittal Plane - ✅✅A Sagittal Plane divides the body or body part into Right or Left sides.
Midsagittal plane - ✅✅A Midsagittal Plane divides the body into equal Right and Left halves.
Frontal (Coronal) Plane - ✅✅Frontal (Coronal) Plane divides the body or body part into Front
(Anterior) to Back (Posterior) sections
Transverse Plane - ✅✅A Transverse (Horizontal) Plane divides the body or body part into Upper
(Superior) and Lower (Inferior) sections.
Directional Terms to Review Include - ✅✅
Superior - ✅✅Superior: Above or closer to the top of the head.
Inferior - ✅✅Inferior: Below or closer to the feet
Anterior - ✅✅Anterior: towards the front
Posterior - ✅✅Posterior: towards the back
, Medial - ✅✅Medial: towards the midline
Lateral - ✅✅Lateral: Away from the midline
Proximal and Distal are terms of Direction and are used in reference to extremities. - ✅✅
Proximal - ✅✅Proximal: means closer to the point of attachment of the extremity to the trunk.
Distal - ✅✅Distal: refers to farther away from the point of attachment of the extremity to the trunk.
Superficial - ✅✅Superficial: means closer to or at the surface of the body
Deep - ✅✅Deep: means further into the body
Major body cavities are divided into the the dorsal cavity, which includes: - ✅✅The Cranial, And the
Spinal Cavities, and the Ventral cavity, Which includes the Thoracic and Abdominopelvic Cavities
Cytology - ✅✅Cytology: Is the study of cells.
The Cell is the Basic Unit Of Life and the building block of Tissues and Organs. - ✅✅
The major parts of the Cells are the - ✅✅Plasma Membrane, Cytoplasm, Nucleus, and Organelles
The Nucleus contains Deoxyribonucleic Acid (DNA). Which is genetic material that codes for proteins. -
✅✅
Proteins are major components of body structures and are part of enzymes and hormones which
regulate all chemical reactions within the body - ✅✅
