1 Learning Objectives *continued from last lesson Chap 7 – Part II (Continuation) The Vertebral Column, Thoracic Cage & Pectoral GirdleLearning 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.3Spinous processVertebral foramenPedicleTransverse processBody2(opening)15
5 Cervical Vertebrae, pg 137C1 (atlas), for example, has no body or spinous processAll 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 138All ________ 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, pgSturdy & 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 vertebraeCoccyxAlso known as ______________Consists of __ fused vertebrae
10 Bones of the Thoracic Cage, pg 142 manubriumsternum7 true ribsCostal cartilageXiphoid processFalse ribsFloating 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 145Label your practice diagram (all parts).
