Answer 1

Normal: a line is able to pass through the middle ear, shoulder joint, midway through trunk, anterior to a line midway through the knee in natural curve that is balanced out.
Kyphosis-Lordosis:
Kyphosis- excessive convex curve in the thoracic vertebrae
Lordosis- excessive concave curve in lumbar spine
Flatback: decrease in the normal lumbar curve, and looks flat
Humped: an enlarged prominence that is formed at the lower region of the neck.

Question 2

Describe what good poster is?

Answer 2

It is a line that goes through the lobe of the ear, The body of the cervical vertebrae, shoulder joint, midway thorough trunk, through the greater trochanter of femur, And anterior to a line midway through the knew, anterior to the lateral malleolus.

Answer 3

Known as the vertebral column or backbone, the spine is a bony structure found in the vertebrates, situated in the dorsal aspect of the torso. The spine houses and protects the spinal cord in its spinal canal. It is composed of 33 vertebrae with 24 articulating vertebrae and 9 fused vertebrae in the sacrum and coccyx. As well as 4 coccygeal bones. The articulating vertebrates are divided into three regions: Cervical (7) Thoracic (12) and Lumbar (5). The 9 fused vertebrae make up the sacrum and coccyx.

Question 4

Name and Describe the 3 regions of the vertebrae, as well as tailbone segments.

Answer 4

Cervical vertebrae:
7 small vertebrates thats support the head and enables it to pivot, allowing it to nod and turn.
Thoracic vertebrae:
12 vertebrae that serves as attachment points for all ribs, they become progressively larger as they descend.
Lumbar vertebrae:
5 thick heavy vertebrae that acts as a main weight bearing due to its weight. It forms a natural curve that balances the spine.
Sacrum:
formed by fusion of 5 bones. It has a triangular shape and is part of the pelvis containing nerve roots.
Coccyx:
The tailbone, it is attached to the sacrum and is the last segment of the vertebral column.
