BIOD 151 M1 Human Anatomy and Physiology Test Questions
And Correct Answers | Latest Update 2026 | Graded A+
1. If a mutation occurs that prevents signaling molecules from binding to their
receptors, what would be the most immediate effect on receptor-mediated
endocytosis?
Increased internalization of substances
No effect on endocytosis
Decreased internalization of substances
Enhanced signaling within the cell
2. What are the three layers of the skin, starting from the outermost layer?
Epidermis, Dermis, Hypodermis
Epidermis, Hypodermis, Dermis
Hypodermis, Dermis, Epidermis
Dermis, Epidermis, Hypodermis
3. Describe the difference between the axial and appendicular regions of the
body.
The axial region includes the head, neck, and trunk, while the
appendicular region includes the limbs.
The axial region is responsible for movement, while the appendicular
region is for support.
The axial region refers to the body's outer layer, while the
appendicular region refers to the inner organs.
The axial region contains the heart and lungs, while the appendicular
region contains the digestive organs.
,4. Describe the role of signaling molecules in receptor-mediated endocytosis.
Signaling molecules only affect the cell's metabolism, not its
membrane.
Signaling molecules are irrelevant in the process of endocytosis.
Signaling molecules bind to specific receptors on the cell
membrane, triggering the internalization of substances.
Signaling molecules directly enter the cell without binding to
receptors.
5. Describe the role of peripheral proteins in the cell membrane.
Peripheral proteins assist in signaling and maintaining the cell's
shape.
Peripheral proteins are involved in DNA replication.
Peripheral proteins are responsible for energy production.
Peripheral proteins form channels for ion transport.
6. What are the three organelles involved in the synthesis, transport, and
shipping of proteins?
Ribosomes, Endoplasmic Reticulum, Golgi Apparatus
Mitochondria, Lysosomes, Nucleus
Nucleus, Ribosomes, Cytoplasm
Endoplasmic Reticulum, Mitochondria, Golgi Apparatus
7. Describe the role of catabolism in the overall metabolic processes of the
body.
, Catabolism is the process of transporting nutrients across cell
membranes.
Catabolism involves breaking down complex molecules into simpler
ones, releasing energy for cellular functions.
Catabolism builds complex molecules from simpler ones, storing
energy for future use.
Catabolism regulates body temperature and maintains homeostasis.
8. If a medical professional is examining a patient using the transverse plane,
what specific view are they obtaining?
A cross-sectional view of the body
A view of the body from the side
A view of the body from above
A view of the body from the front
9. When you reach up to scratch your nose, you have to ____ your elbow.
adduct
abduct
flex
extend
10. Describe the primary function of each of the four basic tissue types in the
human body.
Epithelial tissue absorbs nutrients, connective tissue forms barriers,
muscle tissue generates heat, and nervous tissue regulates blood
flow.
, Epithelial tissue secretes enzymes, connective tissue transports
oxygen, muscle tissue maintains posture, and nervous tissue
processes information.
Epithelial tissue stores energy, connective tissue protects organs,
muscle tissue provides insulation, and nervous tissue produces
hormones.
Epithelial tissue covers surfaces, connective tissue supports and
binds other tissues, muscle tissue facilitates movement, and
nervous tissue transmits signals.
11. If a researcher is studying a disease that affects muscle tissue, which type of
tissue would be primarily impacted and what implications might this have for
the body's overall function?
Connective tissue; it would weaken structural support and integrity.
Epithelial tissue; it would hinder absorption and secretion processes.
Muscle tissue; it would impair movement and physical activity.
Nervous tissue; it would disrupt signal transmission and coordination.
12. When referring to orientation and directional terms, what term best
describes something that is farther from the origin of a body part or the
point of attachment of a limb to the body trunk?
Distal
Medial
Proximal
Dorsal
13. Which two organs are primarily found in the abdominal cavity?
Spleen and pancreas
