1 Learning Objectives *continued from last lesson
Chap 7 – Part II (Continuation) The Vertebral Column, Thoracic Cage & Pectoral Girdle Learning Objectives *continued from last lesson

2 Can you Guess What’s Wrong? (Problems with the Spine)
What’s the condition causing the spine to twist? What’s this condition? And, this condition?

3 Exploring the Spine, page 135
Instructions: Number & count how many vertebrae in each region. How many total bones in the spine?

4 General Vertebral Bone Markings, pg 136
Instructions: Match the bone marking with its anatomical name. 3 Spinous process Vertebral foramen Pedicle Transverse process Body 2 (opening) 1 5

5 Cervical Vertebrae, pg 137 C1 (atlas), for example, has no body or spinous process All vertebrae have a common structural pattern (as seen in previous slide). Vertebrae of each region also have certain characteristics. C2 (axis) has a typical body & spine but also features a knoblike tooth called a “dens” dens

6 Cervical Vertebrae continued
C3 – C7 have the following distinguishable characteristics (fill in your notes as I discuss): 1. The_____ is oval – wider from side to side. 2. Except for C7, the ________ ________ is short and split at the top. 3. Vertebral _____ is large and __________. 4. Each transverse process contains a _________ __________ through which the vertebral arteries pass to service the brain.

7 Thoracic Vertebrae, pg 138 All ________ with the ribs and have 5 other characteristics: 1. Body is heart-shaped and bears two small ______ (small joints) 2. Vertebral _______ is circular. 3. Spinous _______ is long & points sharply downward. 4. With the exception of T11 – T12, the transverse _______ have facets.’ 5. Sup. & inf. articular facets lie in the frontal plane (preventing ________ & extension but allows for rotation).

8 Lumbar Vertebrae, pg Sturdy & larger with 4 other notable characteristics: 1. The ______ and laminae are shorter & thicker than other vertebrae. 2. The spinous ________ are short, flat, and hatchet-shaped. 3. The ______ ________ is triangular. 4.The _____ orientation helps to lock them together.

9 Sacrum, pg 141 Coccyx Forms ___________ wall of the pelvis
Formed by ___ fused vertebrae Coccyx Also known as ______________ Consists of __ fused vertebrae

10 Bones of the Thoracic Cage, pg 142
manubrium sternum 7 true ribs Costal cartilage Xiphoid process False ribs Floating ribs (11-12) NOTE: You may want to label pg 142 in textbook also matching it up with this slide.

11 Bones of the Pectoral (Shoulder)
Consists of: 1. _______ (anteriorly) 2. ________ (posteriorly)

12 Pectoral Bones, pg 145 Label your practice diagram (all parts).

13 Scapula, pg 144 Label ONLY red parts.

14 Practice Review Instructions: Complete questions on pages 133 – 134, 135, 139, 143 – 144 in your textbook, “The Anatomy Assignment”.
