Study Notes

Available Resources for Anatomy Studies

Grant’s Dissector is provided in the lab and serves as a guide for dissections.
Other recommended anatomy resources include:
- Netter Atlas of Human Anatomy
- Moore's Clinical Anatomy
- Thieme Atlas of Anatomy
- McMinn & Abraham's Clinical Atlas of Human Anatomy
Acland's Video Atlas of Human Anatomy available through UA Libraries features videos of real human tissue preparations, enhancing understanding of dissections.

Anatomical Terminology

Directional Terms:
- Superior (cranial): Closer to the head.
- Inferior (caudal): Closer to the feet.
- Medial: Closer to the median plane; Lateral: Further from the median plane.
- Combinations like superomedial and inferolateral provide specificity.
Limb Positioning:
- Proximal: Closer to limb attachment; Distal: Further from attachment.
- Terms also apply to distance along linear structures, such as arteries.
Dorsum: Superior aspect of protruding structures like the tongue or nose; Palmar: Palm of the hand; Plantar: Sole of the foot.
Anatomical Layers:
- Superficial: Closest to the surface; Deep: Closest to the core; Intermediate: Between the two.

Organ Structures and Systems

Anatomical structures are often bilateral, with left and right members, while unilateral structures exist on one side.
Terms include:
- Ipsilateral: Same side; Contralateral: Opposite side.
- Midline: Structures lacking laterality.
The body consists of various anatomical systems organized by structure and function, typically involving distinct cell and tissue types.
Understanding nerve functions is crucial for identifying patient symptoms such as pain or weakness.

Clinical Correlations

Anatomical spaces can accumulate pathological fluid, impacting organ functionality.
Examples: Pneumothorax (air in thoracic cavity) and drainage of pus between rectum and uterus.
Clinical uses of anatomical spaces include peritoneal dialysis, which removes waste products via diffusion.
Synovial Bursae: Closed sacs containing serous fluid to reduce friction around tendons and joints.

Evidence-Based Medicine

Evidence-based decisions in medicine are vital for optimal patient outcomes.
Hierarchy of Evidence:
- Ranks evidence based on scientific merit; Randomized Controlled Trials (RCTs) are deemed the gold standard.
Critical Appraisal: A systematic process for assessing the validity and relevance of medical evidence.

Foundations Overview

The curriculum for Class of 2028 includes disciplines like Pharmacology, Immunology, Physiology, Genetics, Embryology, and Pathological Basis of Clinical Medicine.
The block for AY 2024-2025 is focused on foundational medical concepts.

Introduction to Physiology: Homeostasis

Block Director: James Proffitt, PhD; Session Date: July 29, 2024.
Instructor: Zoe Cohen, PhD; Department of Physiology.
Key instructional methods involve lectures and digital media.

Learning Objectives

Define homeostasis and explore the integration of organ systems in maintaining it.
Investigate examples of organ dysfunction, emphasizing how one impaired organ can affect others.
Outline the physiological steps leading to homeostasis loss in heat stroke, including consequences on organ systems.

Heat Stroke Case Study

Heat stroke can elevate respiratory rates, risking respiratory alkalosis that may lead to metabolic acidosis.
Renal dysfunction in heat stroke may arise from thermal injury, fluid depletion, or rhabdomyolysis, impairing kidney filtration.
The spleen's reduced function due to oxygen deprivation can lead to jaundice and increased infection risk.
Excessive heat compromises GI tract integrity, redistributing blood away from intestines and resulting in potential intestinal hypoxia and dysfunction.

Critical Questions for Discussion

Predict the blood pressure and vital signs of a heat stroke patient upon EMT arrival.
Examine potential causes for seizures in heat stroke cases.
Consider the implications of vital sign changes in the context of organ system interdependence.

Competencies and Curriculum Connections

Covers normal and altered structure/function of major organ systems.
Emphasizes pathology in understanding disease processes and diagnostics.
Integrates basic anatomy and function into practical clinical knowledge.

Neurological Overview

Peripheral nervous system breaks into somatic and visceral components.
Somatic nervous system includes voluntary motor control and conscious sensory feedback, while visceral focuses on involuntary autonomic functions.
The parasympathetic system promotes rest and digest functions, whereas the sympathetic system supports fight or flight responses.

Evidence-Based Decision Making (EBDM)

EBDM follows a structured process: Ask (PICO), Acquire, Appraise, Apply, and potentially Reassess.
PICO framework is essential for formulating clinically relevant questions and searching for evidence.
Encourages lifelong learning through application of knowledge to patient care and ongoing evaluation of clinical outcomes.
