ANATOMY & PHYSIOLOGY
DAY 2
Video: Der mensch als industriepalast
Better depiction of Anatomy or Physiology?
System Function Matching!
• PROTECTS!
Integumentary System
• SUPPORT!• BLOOD CELLS
FORMED WITHIN BONES
Skeletal System
• MOVEMENT!• PRODUCES HEAT
Muscular System
• CONTROL SYSTEM!
Nervous System
• SECRETES HORMONES THAT REGULATE GROWTH, REPRODUCTION, AND METABOLISM
Endocrine System
• TRANSPORTATION!
Cardiovascular System
• DEFENSE!
Lymphatic System
• GAS DELIVERY AND EXCHANGE (O2 AND CO2)
Respiratory System
• PROCESSES FOOD• ABSORBS NUTRIENTS
Digestive System
• EXCRETES WASTES, WATER, AND SALTS
Urinary/Excretory System
• PRODUCES SEX CELLS AND HORMONES
Reproductive System
Male
Female
What is the term for largest classification of anatomy structures?
Gross
• Gross Anatomy– The anatomical position (see
right)– Directional and regional
terms

Anatomical Position
Body erect, feet together, palms facing forward, thumbs away from body.
Note: when talking about right/left, you are talking about the patients right or left side, not your own.
• Axial: head, neck and trunk. Contains dorsal and ventral cavities.
• Appendicular: upper and lower limbs
Divisions of the Body
• Describes the location of one part of the body in relation to another.
Relative Positions
• Superior: above another part or closer to the head
• Inferior: below another body part or closer to the feet
• Anterior (ventral): towards the front of the body (breastbone anterior to spine)
• Posterior (dorsal): towards the back of the body (spine posterior to the breastbone)
• Medial: toward the middle of the body
• Lateral: away from the middle, towards the outer side of the body
• Proximal: closer to the point of attachment to the trunk (elbow is proximal to the wrist)
• Distal: farther from the point of attachment to the trunk (knee is distal to the thigh)
• Superficial: toward or at the body surface• Deep: away from the body surface, more internal
Body planes and sections - cut into sections along a flat surface called a plane
(also called XS – cross section)
(also called coronal)
Body planes
• Body is 3D
• Can be split into three planes
• Sagittal• Coronal• Transverse
Sagittal Plane• Plane splitting the body
into two parts (left and right)
• Sagittal section is a cut made longitudinally along the body
• If it splits into two equal parts = midsagittal
Coronal Plane
• Plane which splits body into anterior and posterior section
• Ie. Facelift
Transverse Plane
• Separates body along horizontal plane
• Also called a cross section
• Will divide an organism into superior and inferior parts
Body Cavities
http://en.wikipedia.org/wiki/File:Scheme_body_cavities-en.svg
Cavities
• Opening within body which protects internal organs, and allows transfer of materials/information
• 2 Divisions– Dorsal– Ventral
Dorsal Cavities
• Made up of two smaller cavities
• 1) Cranial Cavity – holds and protects brain
• 2) Spinal Cavity – column which runs through vertebra and protects spinal chord
Ventral Cavities Thoracic Abdominopelvic
Ventral Cavities• 1) Thoracic – chest area
(holds heart, lungs, and diaphragm)
• 2) Abdominopelvic – lower torso (holds digestive and reproductive organs)
Bovine Pleural Cavity Collapsed Lung in Pleural Cavity
Pleural cavity is the space between the membranes covering the chest wall and lungs.
