Anatomy & Physiology I: Lecture and Laboratory Schedule Overview

Course Overview

This study guide summarizes the lecture and laboratory schedule for a college-level Anatomy & Physiology I course. The schedule outlines the sequence of topics, associated chapters, and laboratory units, providing a roadmap for students to prepare for lectures, labs, and exams.

Lecture Topics and Sequence

Introduction to Anatomy and Physiology

• Definition: Anatomy is the study of body structure; physiology is the study of body function.

• Key Concepts: Levels of organization, homeostasis, anatomical terminology.

• Application: Understanding the body's organization is foundational for all subsequent topics.

The Chemistry of Life

• Definition: Study of chemical principles underlying biological processes.

• Key Concepts: Atoms, molecules, chemical bonds, water, pH, macromolecules (carbohydrates, lipids, proteins, nucleic acids).

• Example: The role of enzymes in metabolism.

The Cell

• Definition: The basic structural and functional unit of life.

• Key Concepts: Cell structure (organelles), membrane transport, cell division.

• Example: Mitochondria as the site of ATP production.

Histology

• Definition: The study of tissues.

• Key Concepts: Four basic tissue types: epithelial, connective, muscle, and nervous tissue.

• Application: Identifying tissue types under the microscope.

The Integumentary System

• Definition: The skin and its accessory structures (hair, nails, glands).

• Key Concepts: Layers of the skin, functions (protection, sensation, thermoregulation).

• Example: The role of melanin in skin color.

The Nervous System

• Subtopics: Introduction to the nervous system, nervous tissue, central nervous system (CNS), peripheral nervous system (PNS), autonomic nervous system (ANS), special senses.

• Key Concepts: Neuron structure and function, organization of the CNS and PNS, reflexes, sensory pathways.

• Example: The role of the sympathetic and parasympathetic divisions in homeostasis.

The Endocrine System

• Definition: Glands and hormones that regulate body functions.

• Key Concepts: Major endocrine glands, hormone mechanisms, feedback loops.

• Example: Regulation of blood glucose by insulin and glucagon.

Bones and Bone Tissue

• Definition: Structure and function of bones and supporting tissues.

• Key Concepts: Bone classification, bone cells, bone growth and remodeling.

• Example: The process of endochondral ossification.

The Skeletal System and Articulations

• Definition: The framework of bones and joints in the body.

• Key Concepts: Axial and appendicular skeleton, types of joints, joint movements.

• Example: Classification of synovial joints (e.g., hinge, ball-and-socket).

Muscle Tissue and The Muscular System

• Definition: Types of muscle tissue and their roles in movement.

• Key Concepts: Skeletal, cardiac, and smooth muscle; muscle contraction mechanisms; major muscle groups.

• Example: The sliding filament theory of muscle contraction.

Laboratory Topics and Sequence

Lab Safety and Introduction

• Lab Safety: Policies and procedures for safe laboratory practice.

• Introduction: Overview of anatomical terminology and body organization.

Regional, Positional, and Directional Terms

• Definition: Standardized terms to describe locations and positions on the body.

• Key Concepts: Anterior/posterior, superior/inferior, medial/lateral, proximal/distal.

Body Cavities, Planes, and Membranes

• Body Cavities: Dorsal and ventral cavities, subdivisions.

• Planes: Sagittal, frontal (coronal), transverse planes.

• Membranes: Serous membranes lining body cavities.

Membrane Transport (Diffusion & Osmosis)

• Diffusion: Movement of molecules from high to low concentration.

• Osmosis: Diffusion of water across a selectively permeable membrane.

• Equation: $J = -D \frac{dC}{dx}$ (Fick's law of diffusion)

The Microscope and Histology

• Microscope Use: Proper handling and focusing techniques.

• Histology: Identification of tissue types under the microscope.

Integumentary System (Lab)

• Skin Structure: Epidermis, dermis, hypodermis.

• Accessory Structures: Hair, nails, glands.

Nervous System (Lab)

• Anatomy of the Brain: Major regions and functions.

• Spinal Cord, Nerves, & Reflexes: Structure and function of the spinal cord, peripheral nerves, and basic reflex arcs.

• Dissection: Sheep’s brain and cow’s eye for hands-on anatomical study.

Skeletal and Muscular Systems (Lab)

• Skeletal System: Identification of bones and bone markings.

• Muscular System: Identification of major muscles and their functions.

Exams and Assessments

• Lecture Exams: Three major exams covering specified chapters, plus a cumulative final exam.

• Laboratory Exams: Two-part midterm and practical assessments on anatomical identification and concepts.

• Quizzes: Periodic quizzes on learning objectives and lab content.
