Transcript of Anatomical Position Sec. 1.9 Anterior/Posterior (ventral/dorsal)
Welcome to BIOS 2310Human Anatomy & Physiology IInstructor: Mr. Todd Templeton
• Today’s Agenda:– Discussion of the syllabus.– Presentation of today’s topics:
• Anatomical Position• Introduction to the Skeletal System• Class will end at 4:40
Anatomical Position
• Proximal: nearer the point of origin.
• Distal: farther from the point of origin.
Shoulder and Thoraxpp. 238 – 239, pp. 234 - 235
• Clavicle• Scapula• Sternum• True Ribs 1 – 7
(vertebrosternal)• False Ribs 8 – 12
vertebrochondral (8 – 10). 11 & 12 are floating or vertebral ribs.
• Costal Cartilage

The Systems of the Human Bodypp. 16 - 17
Transport.
Breaks down nutrients. Produces hormones that regulate cell functions.
Systems of the Human Body
Monitors and maintains our internal environment Exchanges oxygen and
carbon dioxide with blood.
Bone Structure• Structurally, bone is classified into 2 types:• 1) Spongy Bone (pg. 191) Note the trabeculae.
Bone Structure• 2) Compact bone • pp. 191.• Note: we will discuss
the microscopic structure of bone in the next unit.
1: Long Bones (pg. 186)• Longer than wide• Cylinder shaped.• Located in the appendicular
skeleton. • Diaphysis (compact)• Epiphysis (spongy)
2: Short Bones• Cube-like.• Filled with spongy bone, with a thin layer of compact covering it.• No hollow medullary canal present.
4. Irregular Bone
• Usually described as a cross between a flat bone and a short bone.
• Spongy interior. • Vertebrae and some skull bones would be
examples.
Today’s Agenda
• Today we will look at joint structure and function, along with lever systems. Ch. 8
• After lab we will begin preparations for exam #1, which is the next class meeting.
