Indicate whether each statement is true or false. 1. The thoracic cage consists of the thoracic vertebrae, the ribs, and the sternum. True 2. The superior seven pairs of ribs are called true ribs because they directly attach to the sternum through their costal cartilages. True 3. Two of the false ribs, the eleventh and twelfth ribs, are called floating ribs because they do not have a posterior attachment to the spine. True 4. Most ribs have two articulations with the vertebrae, the head articulates with the body and the tubercle articulates with the transverse process. False

Transcript

00:01 So to answer the first question which talks about the spinal cord which can be given as spc spinal cord is a characteristic feature of each vertebrate species and it is moderately flexible series of vertebrae.

00:16 V vertebrae is represented as v.

00:20 Each vertebrae is an irregular bone.

00:24 Every vertebrae has a ventral body which consists of a large anterior portion and and middle portion of this vertebrae is called as the centrum.

00:38 The posterior portion contains an arc which is known as the neural arc.

00:46 The body of the vertebra is consists of cancerous bone which is ausiose in nature.

00:56 So in the given structure a denotes the lamina, b denotes the superior articular processes and the facet.

01:09 Superior articular process given by sap c represents padicil d represents the spinous processes of the typical vertebrae e denotes the transverse process f is the vertebral forum and which can be given as vf and g is the body of the vertebrae now to answer the second part, we have five questions to determine whether it is true or false.

02:00 In the first statement which talks about the mannobrium, the manubrium is found posterior to the zepoid process.

02:10 Hence the given statement is false.

02:17 In b, the floating ribs which can be given as fb.

02:22 The floating ribs are attached to the vertebral column and not to the sternum and that's why they are called as floating ribs...
