Anatomy vs. Physiology. Anatomy : structure Physiology : function The size, shape, and position of a structure directly related to function Ex. The wiring of a window screen allows air to pass through but keeps bugs out. The circular shape of a wheel allows it to roll.

Anatomy vs. Physiology • Anatomy: structure • Physiology: function • The size, shape, and position of a structure directly related to function • Ex. The wiring of a window screen allows air to pass through but keeps bugs out. • The circular shape of a wheel allows it to roll.
How does structure relate to function with regard to: • The skull? • Our hands? • Our joints? • The heart? • The intestines? • A problem with the structure of a body part may affect its function. • Apply this concept to the five structures above
What is disease? Disease: abnormalities of body structure or function that prevent the body from maintaining the internal stability that keeps us alive and healthy a disruption of homeostasis caused by infection, genetics, environmental stress
What is disease? If you break your arm, do you have a disease? Pathology: the scientific study of disease
Nautical Directional Terms Write directions to a specific freckle/spot!
Avast, ye mateys! • Aft: 1: The portion of the vessel behind the middle area of the vessel. 2: Towards the stern (of the vessel). • Amidships (or midships): In the middle portion of ship, along the line of the keel. • Astern/stern: 1: Toward the stern (rear) of a vessel. 2: Behind a vessel. • Bow: The front of a ship. • Fore: Front • Port: left • Starboard: right • Transom: side of ship
Anatomical Directions • Proximal—toward the trunk of the body • Distal—away from the trunk of the body • The shoulder is proximal to the elbow. • The foot is distal to the knee.
In four legged animals: Anterior = toward the head Posterior = toward the tail
Anatomical Directions • Anterior/ventral—front • Posterior/dorsal—back • The patella (kneecap) is anterior to the calcaneus (heel). • The occiput is posterior to the mouth.
Anatomical Directions • Superficial—toward the surface of the body • Deep—away from the surface of the body. • The skin is superficial to the fat. • The heart is deep to the ribcage.
