Skeleton:  Vertebrae & Ribs

Exercise 15

Complete pages 109-116+ drawing of osteon bottom of page 116

This lab is to allow you to become familiar with the anatomy of the vertebrae & the ribs of the skeleton. Look at and label with sticky paper the skeletal models both articulated (put together) & disarticulated (taken apart). 

 

1.  Be able identify  the following vertebrae structures

vertebral column

(+ how many of each)

  cervical

  thoracic

  lumbar

  sacrum

  coccyx

curves

 cervical curvature

  thoracic curvature

  lumbar curvature

  sacral curvature

ligaments

  anterior longitudinal ligaments

 

  posterior longitudinal ligaments

 

vertebrae

  vertebral body

  vertebral arch

  pedicles

  laminae

  spinous processes

  vertebral foramen

  spinous processes

  transverse processes          superior & inferior  processes

intervertebral foramina

intervertebral discs

sacrum:  anterior

  sacral promontory:

  ventral sacral foramina

 

 

sacrum:  posterior

  median sacral crest:

  dorsal sacral foramina

  sacral canal

  sacral hiatus

 

2.  Be able to tell if a vertebrae is one of the following

 

3.  Be able identify  the following thoracic & rib structures


 

thoracic cage

  true ribs

  false ribs

  floating ribs 

(+ how many of each)

sternum

  manubrium

  body

  xiphoid processes

rib

  shaft

  costal groove.

  head of the rib.

  tubercle

 4.  On the bottom of page 116 draw an osteon from a slide.  It MUST have these structures labeled for full credit.
