Anatomy & Physiology Laboratory Study Guide: Key Concepts and Structures

Introduction to Anatomy & Physiology Laboratory

Overview

This study guide outlines the major topics, structures, and concepts that students are expected to master in a college-level Anatomy & Physiology laboratory course. It covers anatomical terminology, tissue types, skeletal and muscular systems, nervous system, and related laboratory skills.

EXAM 1

Language of Anatomy

• Anatomical Position: The standard reference position for the body in anatomical studies: standing upright, facing forward, arms at the sides, palms facing forward.

• Body Landmarks: Key surface features used to identify regions of the body (e.g., Axial, Appendicular).

• Body Planes and Sections:

  • Sagittal Plane: Divides the body into left and right parts.

  • Frontal (Coronal) Plane: Divides the body into anterior and posterior parts.

  • Transverse (Horizontal) Plane: Divides the body into superior and inferior parts.

  • Oblique Plane: Passes through the body at an angle.

• Body Cavities: Spaces within the body that contain organs. Major cavities include cranial, vertebral, thoracic, abdominal, and pelvic cavities.

• Serous Membranes: Thin membranes lining body cavities (e.g., pleura, pericardium, peritoneum).

• Directional Terms: Terms used to describe locations and relationships (e.g., superior, inferior, anterior, posterior, medial, lateral, proximal, distal).

Organization of the Body

• Organ Systems: Groups of organs that work together to perform specific functions (e.g., digestive, respiratory, nervous).

• Body Regions: Specific areas of the body identified for study (e.g., oral, nasal, orbital, middle ear, synovial cavities).

Microscope Use

• Parts of the Microscope: Know the function and identification of each part (e.g., ocular lens, objective lens, stage, coarse/fine adjustment).

• Care and Use: Proper handling, cleaning, and focusing techniques.

Cell Division

• Mitosis: The process by which a cell divides to produce two identical daughter cells. Stages include prophase, metaphase, anaphase, and telophase.

• Cell Cycle: The sequence of events in the life of a cell, including interphase and mitosis.

Tissues

• Histology: The study of tissues.

• Epithelial Tissue: Covers body surfaces and lines cavities. Classified by cell shape and layers (e.g., simple squamous, stratified cuboidal).

• Connective Tissue: Supports, protects, and binds other tissues (e.g., bone, blood, adipose).

• Muscle Tissue: Responsible for movement (e.g., skeletal, cardiac, smooth).

• Nervous Tissue: Conducts electrical impulses; includes neurons and neuroglia.
