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.

3

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

4

Anterior Landmarks

5

PosteriorLandmarks

6

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

7

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

8

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

9

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

10

Body Orientationand 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

11

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

12

Planes of the Body

13

• Dorsal cavity protects the nervous system

• Contains Brain and Spinal Cord

Dorsal Body Cavity

14

Cavities

• Thoracic Cavity• Heart & Lungs

• Subdivided into the mediastinum and pluralcavities

• Lower border is the diaphragm• Abdominal Cavity

• Stomach, Liver, Intestines• Pelvic Cavity

• Reproductive organs Bladder, Rectum

15

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

Serous Membranes of the Heart

Quadrants

• RUQ• Liver

• LUQ• Spleen

• RLQ• Appendix

• LLQ• Sigmoid colon

Organ SystemsMartini Chapter 1, Pages 9-10

21

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

22

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

23

Muscular System

• Structures: The 600+ muscles of the body• Function:

• Locomotion• Manipulation of the environment• Maintaining posture• Thermogenesis (generation of heat)

24

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

25

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.

26

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.

27

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

28

Respiratory System

• Structures:• Nasal cavity, pharynx, trachea, bronchi, lungs

• Functions:• Constantly supply the blood with O2, and remove

CO2

• Regulate blood pH

29

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

30

Urinary System

• Structures:• Kidneys, ureters, urinary bladder,

urethra• Functions:

• Removal of nitrogenous wastes• Regulation of body’s levels of water, electrolytes,

and acidity

31

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

Care of the Microscope1. 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 lowest-power objective and change to higher-power lenses as necessary.

• Use fine focus only for adjustment4. Use coarse adjustment knob only with the lowest

power objective lens5. Always use a coverslip with temporary

preparations

35

Putting Microscope Away1. Remove slides from stage and place in

appropriate place2. Rotate the lowest-power objective lens into

position3. Move stage to the lowest position4. Turn down light brightness5. Turn off power6. Wipe microscope (not the lens) with Kimwipes or

alcohol wipe if needed7. Wrap the cord neatly around the base8. Lock the cabinet
