BMS 507 Lab: Human Anatomy & Physiology I – Student Lab Guide Study Notes

BMS 507 Lab: Human Anatomy & Physiology I

Introduction to the Lab Guide

This lab guide is designed to support your learning in Human Anatomy & Physiology I. It provides an overview of lab structure, practical exam expectations, and strategies for success. The guide covers essential topics such as anatomical terminology, tissue classification, skeletal system, histology, and more, with a focus on hands-on, practical learning.

Lab Structure and Practical Exams

What is a Lab Practical?

• Lab practicals are hands-on, station-based tests where students identify structures, answer questions, and demonstrate understanding of anatomical concepts.

• Each station may include specimens, models, microscope slides, or images, and students answer specific questions at each station.

• Time is limited at each station, requiring efficient observation and recall.

• Questions may involve naming anatomical landmarks, identifying tissue types, or describing the function of a structure.

Example: At a bone station, you may be asked to name a bony landmark, identify the muscle that inserts there, and name the bone itself.

Types of Lab Practical Questions

• Identification of anatomical structures (e.g., bones, muscles, tissues)

• Describing the action, origin, and insertion (AOI) of muscles

• Recognizing tissue types under the microscope (histology)

• Locating structures on models or images

Example: "Name the muscle indicated in blue. Name the insertion point of the muscle marked yellow. Name an action of the muscle that inserts on the bony landmark marked green."

Key Topics Covered in the Lab

1. Language of Anatomy

• Anatomical position: Standard reference position for the body (standing, facing forward, arms at sides, palms forward).

• Directional terms: Used to describe locations of structures (e.g., superior, inferior, anterior, posterior, medial, lateral, proximal, distal).

• Body planes: Imaginary lines dividing the body (sagittal, frontal/coronal, transverse).

Example: The heart is medial to the lungs and superior to the diaphragm.

2. Organ Systems Overview

• Major organ systems: Integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, reproductive.

• Each system has specific organs and functions essential for homeostasis.

Example: The skeletal system provides support and protection, stores minerals, and produces blood cells.

3. The Microscope

• Compound light microscope: Used to view thin sections of tissues and cells.

• Parts of the microscope: Ocular lens, objective lenses, stage, coarse and fine focus knobs, light source.

• Proper use: Start with the lowest power objective, use coarse focus first, then fine focus.

Example: Identifying epithelial tissue under the microscope at 400x magnification.

4. Classification of Tissues (Histology)

• Four basic tissue types: Epithelial, connective, muscle, nervous.

• Epithelial tissue: Covers surfaces, lines cavities, forms glands. Classified by cell shape (squamous, cuboidal, columnar) and layers (simple, stratified).

• Connective tissue: Supports, binds, and protects organs (e.g., bone, cartilage, adipose, blood).

• Muscle tissue: Responsible for movement (skeletal, cardiac, smooth).

• Nervous tissue: Conducts electrical impulses (neurons and neuroglia).

Example: Simple columnar epithelium lines the digestive tract.

5. Skeletal System Overview

• Bone tissue: Specialized connective tissue with a mineralized matrix.

• Axial skeleton: Skull, vertebral column, rib cage.

• Appendicular skeleton: Limbs and girdles (pectoral and pelvic).

• Bony landmarks: Specific features on bones (e.g., foramen, fossa, process, tuberosity).

Example: The foramen magnum is a large opening in the occipital bone for the spinal cord.

6. Joints and Movement

• Joints (articulations): Sites where two or more bones meet.

• Types of joints: Fibrous, cartilaginous, synovial.

• Synovial joints: Freely movable, contain synovial fluid (e.g., shoulder, knee).

• Movements: Flexion, extension, abduction, adduction, rotation, circumduction.

Example: The elbow is a hinge joint allowing flexion and extension.

7. Muscular System: Actions, Origins, Insertions (AOI)

• Action: The movement produced by a muscle (e.g., flexion of the forearm).

• Origin: The fixed attachment point of a muscle.

• Insertion: The movable attachment point of a muscle.

Example: The biceps brachii originates on the scapula and inserts on the radius, producing forearm flexion.

Histology: Identifying Tissues

Microscope Slide Identification

• Recognize tissue types by their cellular arrangement and structure.

• Commonly identified tissues: simple squamous epithelium, stratified squamous epithelium, adipose tissue, hyaline cartilage, bone, skeletal muscle, nervous tissue.

Example: Simple cuboidal epithelium lines kidney tubules.

Strategies for Success in A&P Lab

Preparation and Study Tips

• Read the lab manual and guide ahead of time.

• Review vocabulary and diagrams regularly.

• Practice identifying structures on models, images, and real specimens.

• Use both term and picture when making flashcards.

• Quiz yourself and work with lab partners for reinforcement.

• Stay organized: keep notes, guides, and vocabulary lists together.

Tip: Focus on understanding the objectives and concepts of each lab session, not just memorization.

Sample Table: Types of Epithelial Tissue

Type	Cell Shape	Layers	Location	Function
Simple Squamous	Flat	Single	Alveoli of lungs, lining of blood vessels	Diffusion, filtration
Simple Cuboidal	Cube-shaped	Single	Kidney tubules, glands	Secretion, absorption
Simple Columnar	Tall, column-like	Single	Digestive tract lining	Absorption, secretion
Stratified Squamous	Flat	Multiple	Skin, mouth, esophagus	Protection

Glossary of Key Terms

• Foramen: An opening or hole in a bone for passage of nerves or blood vessels.

• Fossa: A shallow depression in a bone.

• Process: A projection or outgrowth from a bone.

• Origin (muscle): The fixed attachment point of a muscle.

• Insertion (muscle): The movable attachment point of a muscle.

• AOI: Action, origin, and insertion of a muscle.
