Introduction

This study guide summarizes the key topics, anatomical terms, and laboratory exercises covered in the first seven weeks of a college-level Anatomy & Physiology I course. It is organized by week and topic, providing definitions, examples, and essential concepts for exam preparation.

Week 1: Anatomical Terminology and Organ Systems

Anatomical Position and Terminology

• Anatomical Position: The standard reference position for the body in the study of anatomy. The body stands upright, facing forward, arms at the sides with palms facing forward, and feet parallel.

• Surface Anatomy Terms: Used to describe locations on the body. Examples include cephalic (head), axillary (armpit), patellar (kneecap), hallux (big toe), etc.

• Body Planes and Sections:

  • Frontal (coronal) plane: Divides the body into anterior and posterior parts.

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

  • Transverse plane: Divides the body into superior and inferior parts.

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

• Orientation/Direction Terms: Used to describe the location of one body part relative to another.

  • Superior/Inferior: Above/below

  • Ventral (anterior)/Dorsal (posterior): Front/back

  • Medial/Lateral: Toward the midline/away from the midline

  • Proximal/Distal: Closer to/farther from the point of attachment

  • Superficial/Deep: Toward/away from the body surface

• Body Cavities:

  • Dorsal body cavity: Cranial and vertebral cavities

  • Ventral body cavity: Thoracic and abdominopelvic cavities

  • Thoracic cavity: Contains heart and lungs

  • Abdominopelvic cavity: Contains digestive, urinary, and reproductive organs

  • Pericardial cavity: Contains the heart

• Abdominopelvic Regions and Quadrants:

  • Quadrants: Right upper, left upper, right lower, left lower

  • Regions: Right/left hypochondriac, epigastric, right/left lumbar, umbilical, right/left iliac, hypogastric

Organ Systems Overview

• Major Organ Systems: Integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, reproductive

• Major Organs: Examples include heart (cardiovascular), lungs (respiratory), stomach (digestive), kidney (urinary), etc.

Identification of Organs

• Be able to identify organs such as thymus, heart, lungs, trachea, esophagus, diaphragm, liver, gallbladder, stomach, intestines, pancreas, spleen, kidney, ureter, urinary bladder, testis, ovary, uterus, and associated blood vessels on models or specimens.

Week 2: Microscopy, Cells, and Tissues

The Microscope

• Parts of the Microscope: Eyepiece, objective lenses, stage, coarse/fine focus, light source, etc.

• Functions: Each part has a specific function in magnifying and resolving specimens.

• Proper Technique: Includes correct focusing, adjusting light, and handling slides.

• Calculations:

  • Total Magnification:

  • Working Distance: Distance between the objective lens and the specimen.

  • Field Size: The diameter of the area visible through the microscope.

  • Object Size: Can be estimated using field size and proportion of the field occupied.

Cell Structure

• Identify structures on a cell model: plasma membrane, ribosome, Golgi apparatus, smooth/rough ER, mitochondrion, lysosome, centrioles, vacuole, nucleus, nucleolus, chromatin, nuclear envelope.

Cell Division

• Identify stages of mitosis: prophase, metaphase, anaphase, telophase.

Classification of Epithelial Tissues

• Simple squamous, cuboidal, columnar epithelium

• Pseudostratified columnar, stratified squamous, transitional epithelium

• Example: Simple squamous epithelium lines blood vessels; stratified squamous epithelium forms the skin's outer layer.

Week 3: Connective Tissues and Integumentary System

Connective Tissue Types

• Areolar, adipose, dense regular (white fibrous), bone, blood, fibrocartilage, hyaline cartilage, elastic cartilage

• Example: Adipose tissue stores fat; bone tissue provides structural support.

The Integumentary System

• Identify structures: epidermis, dermis, hair shaft/root/follicle, sebaceous gland, arrector pili muscle, sweat glands, dermal papillae, tactile (Meissner's) and lamellar (Pacinian) corpuscles, blood vessels, lymph vessels, adipose tissue.

• Identify epidermal layers: stratum corneum, lucidum, granulosum, spinosum, basale.

• Microscope slides: distinguish skin with/without hair, dermis, epidermis, glands, and sensory structures.

Cartilage and Bone Overview

• Types of cartilage: hyaline, fibrocartilage, elastic

• Example: Hyaline cartilage is found in the nose and trachea; fibrocartilage in intervertebral discs; elastic cartilage in the ear.

Week 4: The Skeleton – Bones and Landmarks

Cranial and Facial Bones

• Identify bones and major landmarks of the skull, including frontal, parietal, temporal, occipital, sphenoid, ethmoid, mandible, maxilla, zygomatic, lacrimal, nasal, vomer, inferior nasal concha, and hyoid.

• Landmarks include sutures, foramina, processes, and fossae.

Vertebral Column

• Regions: cervical (atlas, axis), thoracic, lumbar, sacrum, coccyx

• Landmarks: transverse process, spinous process, vertebral foramen, body, dens (on axis)

Thoracic Cage

• Sternum (manubrium, body, xiphoid process), ribs (true, false, floating)

Shoulder Girdle and Upper Limb

• Clavicle, scapula (spine, acromion, coracoid process, glenoid cavity)

• Humerus (head, tubercles, epicondyles, fossa), ulna (olecranon, notch, styloid process), radius (tuberosity, styloid process)

• Carpals, metacarpals, phalanges

Week 5: Pelvic Girdle and Lower Limb

Pelvic Girdle

• Coxal bone (ilium, ischium, pubis), acetabulum, auricular surface, iliac crest, pubic symphysis, obturator foramen, sacroiliac joint, anterior superior iliac spine

• Comparison: Male pelvis is narrower and deeper; female pelvis is wider and shallower for childbirth.

Thigh, Leg, and Foot

• Femur (head, neck, trochanters, condyles, epicondyles, linea aspera)

• Tibia (tuberosity, condyles, malleolus), fibula (head, malleolus)

• Tarsals (talus, calcaneus, navicular, cuneiforms, cuboid), metatarsals, phalanges

Week 6: Articulations and Body Movements

Classification of Joints

• Fibrous Joints: Joined by fibrous tissue, no joint cavity (e.g., suture of skull, syndesmosis between tibia and fibula, gomphosis in teeth)

• Cartilaginous Joints: Joined by cartilage, no joint cavity (e.g., symphysis at pubic symphysis, synchondrosis at first rib and sternum)

• Synovial Joints: Freely movable, joint cavity present. Types include:

  • Plane joint: Intercarpal joints

  • Hinge joint: Elbow

  • Pivot joint: Atlantoaxial joint

  • Condyloid joint: Radiocarpal joint

  • Ball and socket joint: Shoulder and hip

  • Saddle joint: 1st metacarpal and trapezium
