Lab Activity 1 Language of Anatomy Martini Chapter 1 Portland Community College BI 231
Anatomy • Gross anatomy: the study of body structures visible to the naked eye (without a microscope) • Microscopic anatomy: • Cytology: Analysis of the internal structures of individual cells • Histology: examination of tissues (groups of specialized cells that work together to perform a specific function.
Anytime you describe structures relative to one another, you must assume this standard position: Body erect Feet slightly apart Palms facing forward Thumbs point away from body Anatomical Position
Anatomical Locations • Abdominal: abdominal region • Acromial: the point of the shoulder • Antebrachial: forearm • Antecubital: anterior surface of the elbow • Axillary: armpit • Brachial: upper arm • Buccal: cheek of the face • Calcaneal: heel of the foot • Carpal: wrist • Cephalic: head
Anatomical Locations • Cervical: neck • Deltoid: round part of the shoulder • Digital: fingers and toes • Dorsum: back • Femoral: thigh • Frontal: forehead • Gluteal: buttocks • Hallux: big toe • Inguinal: groin • Lumbar: lower back • Mammary: breast
Anatomical Locations • Mental: chin • Nasal: Nose • Occipital: base of the skull • Olecranal: elbow • Oral: mouth • Orbital: bony eye socket • Otic: ear • Palmar: palm of hand • Patellar: Kneecap • Pedal: Foot
Anatomical Locations • Pelvic: pelvis region • Perineal: area between anus and external genitals • Plantar: sole of foot • Pollex: thumb • Popliteal: behind the knee • Pubic: genital region • Sacral: lower back between the hips • Scapular: shoulder blade • Tarsal: ankle • Thoracic: chest • Vertebral: spine
These are relative positions Proximal/distal Used to describe locations on the arms and legs GI tract Medial/lateral Medial is closer to the midline Farther away from the midline Body Orientationand Direction
Dorsal: Back Ventral: Front Superior or Cephalad is toward the head Inferior or Caudal is toward the feet Anterior: most forward Posterior: toward the backside Body Orientation and Direction
Dorsal cavity protects the nervous system Contains Brain and Spinal Cord Dorsal Body Cavity
Thoracic Cavity Heart & Lungs Subdivided into the mediastinum and plural cavities Lower border is the diaphragm Abdominal Cavity Stomach, Liver, Intestines Pelvic Cavity Reproductive organs Bladder, Rectum Cavities
Serous Membranes • Serous Membranes have two layers • Parietal serosa lines internal body walls • Visceral serosa covers the internal organs • Serous fluid separates the serosae

Lab Activity 2 Organ Systems Martini Chapter 1, Pages 9-10
Integumentary System • Structures: Skin, hair, sweat and oil glands • Function: • Forms external body covering • Protects deeper tissues from injury • Involved in vitamin D synthesis • Prevents desiccation, heat loss, and pathogen entry • Site of pain and pressure receptors
Skeletal System • Structure: 206 bones of the human body • Function: • Protects and supports body organs • Provides a framework that muscles can use to create movement • Hematopoiesis (synthesis of blood cells) • Mineral storage • Bone contains 99% of the body’s store of calcium
Muscular System • Structures: The 600+ muscles of the body • Function: • Locomotion • Manipulation of the environment • Maintaining posture • Thermogenesis (generation of heat)
Nervous System • Structures: Brain, Spinal cord, and peripheral nerves. • Function: • Fast-acting control system of the body • Monitoring of the internal and external environment and responding (when necessary) by initiating muscular or glandular activity • Information Assessment
Endocrine System • Structures: Hormone Secreting Glands • Pituitary, Thyroid, Thymus, Pineal, Parathyroid, Adrenal, Pancreas, Small Intestine, Stomach, Testes, Ovaries, Kidneys, Heart • Functions: • Long-term control system of the body • Regulates growth, reproduction, and nutrient use among other things.
Cardiovascular System • Structures: • Heart, Blood vessels (arteries, veins, and capillaries) • Functions: • The heart pumps blood thru the blood vessels. • Blood provides the transport medium for nutrients (glucose, amino acids, lipids), gases (O2, CO2), wastes (urea, creatinine), signaling molecules (hormones), and heat.
Lymphatic/Immune System • Structures: • Lymphatic vessels, Lymph nodes, Spleen, Thymus, Red bone marrow • Functions: • Returning “leaked” fluid back to the bloodstream • Disposal of debris • Attacking and resisting foreign invaders (pathogens i.e., disease-causing organisms) • Absorption of fat from the digestive tract
Respiratory System • Structures: • Nasal cavity, pharynx, trachea, bronchi, lungs • Functions: • Constantly supply the blood with O2, and remove CO2 • Regulate blood pH
Digestive System • Structures: • Oral cavity, esophagus, stomach, small intestine, large intestine, rectum, salivary glands, pancreas, liver, gallbladder • Functions: • Ingestion and subsequent breakdown of food into absorbable units that will enter the blood for distribution to the body’s cells
Urinary System • Structures: • Kidneys, ureters, urinary bladder, urethra • Functions: • Removal of nitrogenous wastes • Regulation of body’s levels of water, electrolytes, and acidity
Reproductive System • Structures: • Male: • Testes, scrotum, epididymis, vas deferens, urethra, prostate gland, seminal vesicles, penis • Female: • Ovary, uterine tube, uterus, cervix, vagina, mammary glands • Functions: • Making Babies
Lab Activity 3 The Microscope
Care of the Microscope • When transporting microscope, hold in upright position with one hand on the arm and the other supporting the base • Only use lens paper to clean the lens. NEVER USE KIMWIPES. • Always begin the focusing process with the lowest-power objective and change to higher-power lenses as necessary. • Use fine focus only for adjustment • Use coarse adjustment knob only with the lowest power objective lens • Always use a coverslip with temporary preparations
Putting Microscope Away • Remove slides from stage and place in appropriate place • Rotate the lowest-power objective lens into position • Move stage to the lowest position • Turn down light brightness • Turn off power • Wipe microscope (not the lens) with Kimwipes or alcohol wipe if needed • Wrap the cord neatly around the base • Lock the cabinet
