How do vertebral columns of man and pig differ?
The main difference between the vertebral columns of humans and pigs is the number of vertebrae. Humans typically have 33 vertebrae, while pigs have 24-25. Additionally, the shape and size of the vertebrae may vary slightly, but the overall structure and function are similar in both species.
Another name for the spine?
Actually its still spine. The spine in anatomy is the combination of the vertebral column (the bone part) and the spinal chord (the nervous tissue part). that may be all right and so but there is still another wscientific word for spine and and that is dorsal and lumber vertebrate
How many bones are there in an adult human backbone?
The human adult vertebral column consists of 26 bones. There are 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, and 2 that are collections of fused bones, the sacrum and the coccyx. An infant may have 32, 33, or 34 spinal bones present at birth.
What is a trait that is ancestral to all chordates?
A notochord is a trait ancestral to all chordates. It is a flexible rod-like structure that provides support along the body axis and may persist in some chordates throughout their entire life, while in others it is replaced by the vertebral column.
What fracture in which the bone is crushed common in the vertebral column?
A compression fracture is common in the vertebral column, where the bone is crushed or collapsed due to excessive force or trauma. This type of fracture often occurs in individuals with osteoporosis or from high-energy accidents like falls from a height or car accidents. Treatment may involve pain management, bracing, and sometimes surgery to restore stability.
How many bones are in a Human Neck?
Seven. They compose the seven cervical vertebrae. There is another bone in the neck, which is really part of the function of the tongue called the hyoid. Though not considered a neck bone in function it is located in the neck.But, it's not just humans. In fact, all mammals have the same number of bones in their neck, seven, even giraffes.The most common answer is that there are seven vertebra in the neck section of the human spine.There's 28 bones in the human neck (8 cranial, 14 facial, and 6 ear bones).There is some confusion of how many vertebrate there are in the human vertebral column. Neck vertebrate:7 Thoracic vertebrate: 12 Lumbar vertebrate: 5 Sacrum vertebrate: 5 Coccyx vertebrate: 4 The 5 vertebrate of the Sacrum are fused, and may be counted as one. The 4 verterbrate of the Coccyx are also fused, and may be counted as one. This brings the total to 26 or 33.There is some confusion of how many vertebrate there are in the human vertebral column.

Does an arthropod have a backbone?
Arthropods don't have backbones. The vertebral column or spine comprises individual bones (vertebrae) as part of an internal skeleton or endoskeleton. Arthropods by contrast have no bony internal skeleton, instead they rely on a chitinous external or exoskeleton, consequently they also evidence the joint appendages and segmented body which characterize the phylum.
What is the axial skeleton and what belongs to it?
The axial skeleton consists of the 80 bones in the head and trunk of the human body. It is composed of five parts; the human skull, the ossicles of the inner ear, the hyoid bone of the throat, the rib cage, and the vertebral column. The axial skeleton and the appendicular skeleton together form the complete skeleton.
What are the 3 vertebral disorders?
The most common disorders affecting the spine are degenerative, most often following trauma such as hard labour or whiplash. In spondylosis, bony spurs called osteophytes project from vertebrae and become denser, and vertebral disks degenerate and protrude. More commonly protrusion of a vertebral disk causes the spinal canal to narrow, distorts the local ligaments, and compresses an emerging nerve root, resulting in pain, weakness, and numbness in the area. Lumbar spinal stenosis is a condition characterized by the narrowing of a few segments of the spinal canal when the vertebrae, disks, and ligaments protrude, compressing the nerve roots
What can take up residence at the end of the vertebrae column?
At the end of the vertebral column, the coccyx, commonly known as the tailbone, is located. It is composed of several fused vertebrae and serves as an attachment point for various muscles and ligaments. Additionally, in some cases, conditions like a pilonidal cyst can develop in this area, which may require medical attention.
How does the whiplash injury affect the anterior longitudinal ligament that may be damaged when whiplash occurs?
A torn ligament can lead to vertebral disc herniation or to excessive movement of the spinal column which can result in pain spasms, cracking/grinding in the neck, or numbness in feet and hands.
What can be the origin of back pain?
It may originate from the bones and ligaments forming the spine, the muscles and tendons supporting the back, the nerves that exit the spinal column, or even the internal organs.
