1Learning Objectives *continued from last lesson Chap 7 – Part II (Continuation) The Vertebral Column, Thoracic Cage & Pectoral GirdleLearning Objectives*continued from last lesson
2Can 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?
3Exploring the Spine, page 135 Instructions: Number & count how many vertebrae in each region.How many total bones in the spine?
4General Vertebral Bone Markings, pg 136 Instructions: Match the bone marking with its anatomical name.3Spinous processVertebral foramenPedicleTransverse processBody2(opening)15
5Cervical 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
6Cervical 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.
7Thoracic 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).
8Lumbar 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.
9Sacrum, pg 141 Coccyx Forms ___________ wall of the pelvis Formed by ___ fused vertebraeCoccyxAlso known as ______________Consists of __ fused vertebrae
10Bones 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.
11Bones of the Pectoral (Shoulder) Consists of:1. _______ (anteriorly)2. ________ (posteriorly)
12Pectoral Bones, pg 145Label your practice diagram (all parts).
