QUESTION
Microscopic vs Gross Anatomy
Answer:
Microscopic Anatomy: Study of structures too small to be seen with the naked eye (e.g., cells,
tissues). Gross Anatomy: Study of large structures visible to the naked eye (e.g., organs, bones).
QUESTION
Negative vs Positive Feedback
Answer:
Negative Feedback: Reverses a deviation to maintain homeostasis (e.g., temperature regulation).
Positive Feedback: Enhances the original stimulus (e.g., childbirth).
QUESTION
Atoms to Organisms Hierarchy
Answer:
Levels: Atoms ’ Molecules ’ Organelles ’ Cells ’ Tissues ’ Organs ’ Organ Systems ’ Organism.
Example: Oxygen atom ’ Water molecule ’ Mitochondrion ’ Muscle cell ’ Muscle tissue ’ Heart ’
Circulatory system ’ Human.
QUESTION
Anatomical Position
Answer:
Definition: Body standing upright, facing forward, arms at sides, palms facing forward, feet
slightly apart. Importance: Standard reference position for anatomical terminology.
QUESTION
Homeostasis
Answer:
Definition: Maintenance of stable internal conditions. Examples: Body temperature regulation,
blood pH, glucose levels. Mechanism: Primarily involves negative feedback loops.
QUESTION
Body Cavities and Their Contents
Answer:
Dorsal Cavity: Cranial (brain) and vertebral (spinal cord). Ventral Cavity: Thoracic (heart, lungs)
and abdominopelvic (digestive organs, reproductive organs).
, QUESTION
Needs of the Body
Answer:
Essential Needs: Nutrients, oxygen, water, stable body temperature, atmospheric pressure.
Function: Crucial for cellular function and overall survival.
QUESTION
Sectioning of the Body (Planes)
Answer:
Sagittal Plane: Left and right sections. Frontal (Coronal) Plane: Anterior and posterior sections.
Transverse Plane: Superior and inferior sections. Oblique Plane: Diagonal cuts.
QUESTION
Negative Feedback Mechanism Pathway
Answer:
Example Pathway: Body temperature rises ’ Thermoreceptors detect change ’ Hypothalamus
(control center) ’ Sweat glands (effectors) activated ’ Body cools down.
QUESTION
Positioning in the Body
Answer:
Supine Position: Lying face up. Prone Position: Lying face down. Lateral Recumbent Position:
Lying on the side. Importance: Used in medical procedures and imaging.
QUESTION
Location Terminologies (Proximal, Distal, etc.)
Answer:
Superior: Toward the head. Inferior: Away from the head. Proximal: Closer to the point of
attachment. Distal: Farther from the point of attachment. Medial: Toward the midline. Lateral:
Away from the midline. Superficial: Toward the surface. Deep: Further from the surface.
QUESTION
Microscopic Anatomy
Answer:
The study of structures too small to be seen with the naked eye, typically using a microscope.
