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.
2
Anatomical Position
• 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

9
Body Orientation
and Direction
• 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
10
Body Orientation and 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
11
Planes of the Body
12
Dorsal Body Cavity
• Dorsal cavity
protects the nervous
system
• Contains Brain and
Spinal Cord
13
Cavities
• 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
14
Serous Membranes
•
Serous Membranes have two layers
1. Parietal serosa lines internal body walls
1. Visceral serosa covers the internal organs
•
Serous fluid separates the serosae

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
21
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
22
Muscular System
• Structures: The 600+ muscles of the body
• Function:
•
•
•
•
Locomotion
Manipulation of the environment
Maintaining posture
Thermogenesis (generation of heat)
23
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
24
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.
25
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.
26
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
27
Respiratory System
• Structures:
• Nasal cavity, pharynx, trachea, bronchi, lungs
• Functions:
• Constantly supply the blood with O2, and remove
CO2
• Regulate blood pH
28
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
29
Urinary System
• Structures:
• Kidneys, ureters, urinary bladder,
urethra
• Functions:
• Removal of nitrogenous wastes
• Regulation of body’s levels of water, electrolytes,
and acidity
30
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
33
Care of the Microscope
1. When transporting microscope, hold in upright
position with one hand on the arm and the other
supporting the base
2. Only use lens paper to clean the lens. NEVER
USE KIMWIPES.
3. Always begin the focusing process with the lowestpower objective and change to higher-power
lenses as necessary.
•
Use fine focus only for adjustment
4. Use coarse adjustment knob only with the lowest
power objective lens
34
5. Always use a coverslip with temporary
Putting Microscope Away
1. Remove slides from stage and place in
appropriate place
2. Rotate the lowest-power objective lens into
position
3. Move stage to the lowest position
4. Turn down light brightness
5. Turn off power
6. Wipe microscope (not the lens) with Kimwipes or
alcohol wipe if needed
7. Wrap the cord neatly around the base
8. Lock the cabinet
