Several marine animals have a dorsal fin.
The concept of dorsal comes from the Latin word dorsuālis . This is what is linked to the back or back . For example: “The child was born with a defect in the spine,” “This species is characterized by the size of its dorsal fin,” “I have had severe pain in the dorsal area for several days.”
In the field of anatomy , the structure that is behind the frontal plane is classified as dorsal. The dorsal region , therefore, is the one that remains behind if an imaginary division of the body in half is made vertically, advancing perpendicular to the ground (in the case of bipeds), or that is furthest from the surface if the body is divided in half horizontally with an imaginary cut parallel to the ground (in the case of quadrupeds).
Certain marine animals, on the other hand, have a fin in their dorsal region that is called, precisely, dorsal fin . Killer whales and sharks , among other species, have a dorsal fin.
The spine
The spine , also called the vertebral column , is the structure that extends from the pelvis to the head, passing through the back and neck. It protects the spinal cord, provides support to the skull and allows humans to remain upright and move bipedally.
Among the most serious injuries that a human being can suffer are those to the spine and brain, the consequences of which can be terrible for the body and mind. Statistics indicate that around eleven thousand people suffer one of these injuries for the first time each year ; By June 2006, on the other hand, it was estimated that nearly two hundred and fifty-three thousand people - almost all of them under 30 years of age - were living with these disorders.
In some regions, the shirt with a number used in sports is called a bib number.
Injuries and recovery
As if the physical problems caused by injuries to the spine and brain were not serious enough, the impact on an emotional level is also very strong , since the subject loses autonomy and feels that they cannot continue with their daily activities. This brings us to the consequences in the student and work spheres: many patients abandon their studies due to difficulties concentrating and moving, and others lose their jobs because their employers are not willing to keep them if they do not perform at a "normal" level.
A traumatic event (such as a car accident, a slip or trip while playing sports, working in construction, or simply walking down the street) can cause damage to the spine that creates a lot of pressure, or sever the fibers of the spine. its nerves and tracts. Since the spine is responsible for communicating the brain with the rest of the body to control movements and sensations, an injury of this type can change our lives completely.
It is important to note that it is not easy to diagnose an injury of this type, since it shares some of its symptoms with other disorders, such as the following: memory loss, paralysis, orientation problems, blurred vision, speech disorders, incontinence of the bladder or bowel, impairment of sexual function, behavioral disturbances. Furthermore, the relationship between the injuries and the accident that caused them is not always evident.
Dorsal as a t-shirt
In some countries, the shirt with a number on the back used in the field of sports is called a bib number.
“The young Frenchman will wear the number 10 of the Madrid team”, “Being able to wear this number is a dream for me” y “The local federation has already confirmed the numbers that the footballers will use in the next international tournament” son expresiones que muestran esta acepción.
