The carina occurs at the lower end of the trachea - usually at the level of the 4th to 5th thoracic vertebra. [3] [4] This is in line with the sternal angle, but the carina may raise or descend up to two vertebrae higher or lower with breathing. The carina lies to the left of the midline, and runs antero-posteriorly (front to back). [citation ...
The cough receptors or rapidly adapting irritant receptors are located mainly on the posterior wall of the trachea, larynx, and at the carina of trachea, the point where the trachea branches into the main bronchi.
Evidence from subcortical small infarcts suggests that motor fibers are somatotopically arranged in the human corona radiata. Following subtotal brain damage, localization of the corticofugal projection in the corona radiata and internal capsule can assist in evaluating a patient's residual motor capacity and predicting their potential for functional restitution.
Embryonic vertebrate subdivisions of the developing human brain hindbrain or rhombencephalon is a developmental categorization of portions of the central nervous system in vertebrates. It includes the medulla , pons , and cerebellum .
The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...

The average amount, 4,800 micrograms per gram of microplastics in brain tissue, was found to be the same as the amount found in a standard plastic spoon, according to the study.
A man in France continues to puzzle scientists nearly a decade after he was found to be living with just 10 percent of a typical human brain. His case was originally published in The Lancet ...
