Anatomy & Physiology: Chapter 1 Notes

The course is designed to span two semesters (Fall and Spring) and lays the foundation for anatomy and physiology.
Goal: understand structure and function; anatomy and physiology are interdependent and inseparable in living systems.
In lectures, emphasis is on physiology; in labs, emphasis is on anatomy through models, dissections, slides, and identification.
Lab activities include identifying structures; students often learn locations themselves and should practice with models and dissections.
Resources include Pearson (2D/3D representations) to help bridge model visuals with real anatomy.

Anatomy (structure) and physiology (function) go hand in hand; you cannot have physiology without anatomy, and you cannot have anatomy without physiology; both are needed to describe a living organism.
The course will introduce anatomical structures first and then discuss physiology, while frequently addressing what can go wrong (pathophysiology) for each structure.

Lectures center on physiology; labs focus on anatomy and identification.
The chapter order typically introduces anatomy (structure) before physiology (function), but practical understanding requires integrating both.
Lab work emphasizes identifying structures in real specimens; there is a push to move from two-dimensional representations to three-dimensional understanding to prepare for clinical settings.
There will be occasional guidance to explore anatomical details on external platforms (e.g., Pearson) to supplement in-class learning.

Humans vary slightly in both external and internal anatomy; major variations exist across individuals.
Roughly
$90\%$ of anatomical structures are identical from person to person; the rest show individual variation.
Variation beyond typical anatomy is a key pathway to understanding pathology; the instructor notes that the list of pathologies is large and not exhaustive.
Extreme variability can affect viability in certain contexts (e.g., congenital anomalies or pregnancy-related outcomes) — such variations can render life non-viable in some cases.

The human body is a highly translational-focused subject; the course emphasizes applying anatomical and physiological knowledge to real-world clinical contexts.
Emphasis on bridging model-based understanding (2D/3D visuals) with actual tissue and clinical situations to build comfort and competence for future clinical work.

Anatomy includes sex-based differences related to male and female biology; references the X and Y chromosome focus in development.
Intersex individuals exist; there are variations between sexes, which the course acknowledges.
The instructor cautions not to dwell too long on gender as a psychosocial construct; a related course exists: "The Wild Biology of Sex and Gender" (taught by Professor Young).
Genetics and development contribute to a spectrum of sex- and gender-related traits; biology recognizes a continuum rather than a strict binary.

There are multiple levels of anatomical description: surface anatomy, external features, and deeper internal structures.
The course emphasizes how these levels relate to function and how they integrate within the broader physiological context.

A strong emphasis on transitioning from two-dimensional and model-based understanding to real tissues and clinical applicability.
Students are encouraged to explore real-world anatomy beyond the classroom through available resources and labs.

Course spans $2$ semesters and blends anatomy and physiology.
Anatomy and physiology are interdependent and must be learned together.
Lab work emphasizes identification and real-tissue understanding; lectures emphasize physiology.
Human anatomy is largely consistent across individuals, with variation that can inform pathology.
Extreme variations can impact viability; understanding these limits is part of clinical relevance.
There is a gender/sex dimension in anatomy, with acknowledgment of intersex variations and a broader discussion linked to a separate course on sex and gender.
Genetics provide a spectrum of traits; many concepts in anatomy/physiology are contextualized within real-world human variation and clinical relevance.

Duration: $2$ semesters.
Proportion of identical anatomy across individuals: $\approx 0.9$ or $90\%$ .
Variability beyond typical anatomy contributes to pathology and clinical considerations.
