Anatomy & Physiology I Q&A | Anatomy
1. The study of the structure of the body and the relationships of its parts to
each other is called:
A) Physiology
B) Histology
C) Anatomy
D) Cytology
Correct Answer: Anatomy
Rationale: Anatomy is the study of the structures of the body and their
relationships to each other. Physiology is the study of how these body parts
function.
2. The directional term meaning "toward the front of the body" is:
A) Posterior
B) Superior
C) Anterior
D) Medial
Correct Answer: Anterior
Rationale: Anterior (or ventral) means toward the front of the body. Posterior
(or dorsal) means toward the back. Superior means toward the head, and
medial means toward the midline.
3. The heart is located in which body cavity?
A) Cranial cavity
B) Abdominopelvic cavity
C) Thoracic cavity
D) Spinal cavity
Correct Answer: Thoracic cavity
,Rationale: The thoracic cavity is the superior portion of the ventral cavity,
which contains the heart and lungs. The heart is specifically located in the
pericardial cavity within the thoracic cavity.
4. The smallest stable unit of matter is a(n):
A) Atom
B) Molecule
C) Cell
D) Tissue
Correct Answer: Atom
Rationale: An atom is the smallest unit of matter that retains the properties
of an element. Molecules are made of atoms, and cells are made of
molecules.
5. A chemical bond formed by the sharing of a pair of electrons between two
atoms is called a:
A) Ionic bond
B) Covalent bond
C) Hydrogen bond
D) Peptide bond
Correct Answer: Covalent bond
Rationale: A covalent bond is formed when two atoms share one or more
pairs of valence electrons. Ionic bonds are formed through the transfer of
electrons.
6. Water molecules are polar because:
A) They have a linear shape
B) Oxygen is more electronegative than hydrogen
C) They share electrons equally
,D) They form ionic bonds
Correct Answer: Oxygen is more electronegative than hydrogen
Rationale: Water is a polar molecule because oxygen is more electronegative
than hydrogen, creating a partial negative charge on the oxygen and partial
positive charges on the hydrogens.
7. The monomers that make up proteins are:
A) Monosaccharides
B) Fatty acids
C) Amino acids
D) Nucleotides
Correct Answer: Amino acids
Rationale: Proteins are polymers made of amino acid monomers. There are
20 different amino acids that can be combined to form a vast number of
proteins.
8. The organelle responsible for generating ATP (cellular energy) is the:
A) Ribosome
B) Golgi apparatus
C) Mitochondrion
D) Endoplasmic reticulum
Correct Answer: Mitochondrion
Rationale: The mitochondrion is the site of cellular respiration and is
responsible for generating ATP through the breakdown of glucose and other
nutrients.
9. The organelle that modifies, sorts, and packages proteins for secretion is
the:
A) Rough endoplasmic reticulum
, B) Smooth endoplasmic reticulum
C) Golgi apparatus
D) Lysosome
Correct Answer: Golgi apparatus
Rationale: The Golgi apparatus modifies, sorts, and packages proteins and
lipids for transport to their final destinations. It is a key component of the
endomembrane system.
10. The movement of water across a selectively permeable membrane is
called:
A) Diffusion
B) Osmosis
C) Active transport
D) Facilitated diffusion
Correct Answer: Osmosis
Rationale: Osmosis is the diffusion of water across a selectively permeable
membrane from a region of higher water concentration (lower solute
concentration) to a region of lower water concentration (higher solute
concentration).
11. A solution that has a higher solute concentration than the inside of a cell
is called:
A) Hypotonic
B) Hypertonic
C) Isotonic
D) Cytotonic
Correct Answer: Hypertonic
Rationale: A hypertonic solution has a higher solute concentration than the
cell's interior. Water will leave the cell by osmosis, causing the cell to shrink.
