Answer:
1. Transverse foramina present: Cervical
2. No canals or foramen present. It articulates superiorly with the sacrum: Coccyx
3. Receive the most stress: Lumbar
4. Attach to ribs: Thoracic
5. Articulates with hip bones of the pelvis: Sacrum
Explanation:
The vertebral column is a <u>series of 33 bones called vertebrae</u> that play a key role in organ protection, movement of body, and overall support. The column has been divided into <u>5 different regions</u> with the number of bones.
<u><em>1. Cervical Vertebrate</em></u><u>:</u> These are the group of <u>seven vertebrae of the neck</u>, start immediately below the skull. Two cervical bones C1 and C2 are unique in function. They are responsible for the movement of the head. They have <u>transverse foramina</u> which <u>gives passage to vertebral artery and vein</u>.
<em><u>2. Thoracic Vertebrae:</u></em> They are a group of twelve small bones that form the vertebral spine in the upper trunk. The function of the thoracic vertebrae is to articulate with ribs to produce the bony thorax.
<em><u>3. Lumbar Vertebrae: </u></em>This is the largest segment of the vertebral column that consists of 5 bones between the rib cage and pelvis. They <u>carry all of the upper body weight</u> providing flexibility and movement to the trunk region. This is why it can <u>receive the most stress easily</u>.
<em><u>4. Sacrum Vertebrae: </u></em>There are 5 sacral vertebral fused bones. It <u>connects to the hip bones and play role in forming a strong pelvis</u>.
<em><u>5. coccyx Vertebrae:</u></em> These are a group of 4 fused bone. There is <u>no vertebral canal due to a lack of vertebral arches</u>. They <u>provide </u>an <u>attachment site for muscles</u> ligament and tendons. They also <u>play a role in stabilization and support</u> while sitting.
Answer:
A dermatome represents the unilateral area of skin on the body that is innervated by fibers from the sensory portion of a single spinal nerve coming from the spinal cord. Each spinal nerve contains spinal roots (anterior and posterior) that come together to form the spinal nerve.
Explanation:
Atoms of different elements always combine in the same way.
John Dalton noted that if the components are added to one exacerbated, the share of their masses will dependably be the same. Dalton's been an English scholar. The component mass of that mix is measured by the confirmation of the presence of molecules assembled by John Dalton.
Answer: The shape of the skull and the supraorbital height tell us the following about each species-
- It can tell us about the intelligence of species and what all senses they were dependent upon for their survival
- Most of the species possess similar skulls as mostly their structures are oval shaped, sloped or round shaped.
- Species have different food habits that is determined by the teeth, which vary from long and dull to short and dull.
- Variation in teeth and face shapes could also be due to different geological locations.
- In particular, the foramen magnum be located where the spine connects can be attributed to how the species gathered food through hunting and what kind of food they sought after.
- Overall, the shape and the supraorbital height of each skull informs us the advantages and disadvantages each species had in its ecosystem.
- It also tells what probable causes of death would be when the species died.
