HESI A2 Anatomy & Physiology Practice Test
The HESI A2 Anatomy and Physiology Test will consist of 25 questions related to Anatomical Planes and Direction; Histology; Mitosis and Meiosis; and Body Systems. Each subsection will cover further related topics specific to those areas. Additional information and sample questions for each subsection are as follows.
Anatomical Planes and Direction
This subsection consists of questions related to the three primary body planes: transverse (horizontal), sagittal, and coronal (frontal). Additionally, you will see questions related to terms of direction, including medial, lateral, proximal, anterior, posterior, etc. For example:
- Superior refers to:
- The hindquarters
- Structures toward the center of the body
- Closer to the head
- Closer to the feet
The correct answer is: c. Closer to the head. Make sure to study all terms and concepts related to anatomical planes and direction.
This subsection contains questions related to structural organization, as well as the importance of cells, tissues, organs, systems, and related concepts and terms. For example:
- All cells consist of ___ and ___ and are able to synthesize proteins.
- DNA and RNA
- Nucleic acid and cytoplasm
- Cell membranes and sex organs
- Tendons and ligaments
- Connective tissues refer to:
- Layers of skin and membranes
- Smooth muscle cells and skeletal muscles
- Bone tissue, fat, blood, ligaments, tendons, and blood vessels
- Bone tissue, blood, fat, ligaments, cartilage, tendons, and lymph
The correct answer to the first question is: a. DNA and RNA. The correct answer to the second question is: d. Bone tissue, blood, fat, ligaments, cartilage, tendons, and lymph.
Mitosis and Meiosis
This subsection contains questions related to mitosis and meiosis and their phases, including interphase, prophase, metaphase, anaphase, telophase, and cytokinesis. Additionally, you will see questions related to haploid and diploid cells, genetic diversity, and other related terms and concepts. For example:
- Interphase refers to:
- The thickening of the chromatin into chromosomes and the disintegration of the nuclear membrane during the formation of cytoskeleton parts
- The preparation of the cell for division by replication of its cytoplasmic and genetic material
- The pulling apart of sister cells into daughter chromosomes
- The splitting of the cell into two cells, in which the cell begins to furrow
- During the first phase of meiosis, chromosomes…
- Cross over and exchange genetic material, forming four chromatids
- Cross over and disintegrate into chromosomes
- Split into daughter cells, which are haploid
- Revert to chromatic as the cellular membrane is pinched
The correct answer to the first question is: b. The preparation of the cell for division by replication of its cytoplasmic and genetic material. The correct answer to the second question is: a. Cross over and exchange genetic material, forming four chromatids.
This subsection consists of questions related to body systems: the integumentary system, including layers of the skin, thermoregulation, and sebaceous and sweat glands; the skeletal system, including compact bone, spongy bone, and skeletal system functions; the muscular system, including types of muscle tissue, skeletal muscle contraction, and thermoregulation; the nervous system, including reflex arc and stimulus, autonomic nervous system, homeostasis, and neurons; the endocrine system, including major endocrine glands; the circulatory system, including red and white blood cells, platelets, the heart, and blood pressure; the respiratory system, including functions and breathing; the digestive system, including movement, secretion, digestion, absorption, small and large intestine, and the alimentary canal; the renal system, including kidney functioning, and the urinary tract; and the reproductive system, including the male and female reproductive systems and functions. For example:
- The adrenal cortex functions to:
- Raise and lower blood sugar and carbohydrate metabolism
- Raise and lower blood pressure
- Regulate growth and development
- Monitor blood sugar level and aid in protein and lipid metabolism
- The sympathetic nervous system functions to:
- Regulate emergency or stressful situations
- Return the body to a normal state following emergency or stressful situations
- Control the five senses
- Control the movement of the skeletal system
The correct answer to the first question is: d. Monitor blood sugar level and aid in protein and lipid metabolism. The correct answer to the second question is: a. Regulate emergency or stressful situations. Make sure to study all related terms and concepts with regard to the body’s systems.
