This would result in a Traumatic Brain Injury, or TBI. There are many different types of brain injury, depending upon the severity of the force upon the head, as well as which portion of the brain is affected. To simplify, brain injuries can be classified as traumatic or acquired, with additional types under each heading. All brain injuries are described as either mild, moderate, or severe. Traumatic Brain Injury Traumatic brain injury is a result of an external force to the brain that results in a change to cognitive, physical, or emotional functioning. The impairments can be temporary or permanent. Types of traumatic brain injury include: * Diffuse axonal injury. Shaking or strong rotation of the head causes brain structures to tear. Nerve tissue is disturbed throughout the brain. * Concussion. Caused by a physical force to the head that causes blood vessels to stretch and cranial nerves to be damaged. * Contusion. A result of a direct impact to the head, which causes bleeding on the brain. * Coup-contrecoup injury. The force to the brain is large enough to cause contusion at the side of impact, as well as the site opposite impact. * Penetration injury. The impact causes a foreign object to penetrate the skull. Acquired Brain Injury An acquired brain injury is an injury to the brain that is not hereditary, congenital, degenerative, or the result of birth trauma. Acquired brain injury generally affects cells throughout the entire brain. Types of acquired brain injury include: • Axnoxic brain injury. This occurs when the brain doesn't receive oxygen.
• Hypoxic brain injury. This occurs when the brain receives some, but not enough, oxygen. Levels of Brain Injury The Glascow Coma Scale is used to describe the level of initial injury relative to the neurological severity caused to the brain. Mild traumatic brain injury occurs when loss of consciousness does not occur or occurs very briefly, and testing or scans of the brain seem normal. Moderate traumatic brain injury occurs when loss of consciousness lasts a few minutes to a few hours, confusion lasts for days or weeks, and physical, cognitive, and behavioral impairments are evident. Severe brain injury occurs when unconsciousness or coma lasts days, weeks, or months, and is characterized by permanent physical, cognitive, or emotional impairments.
What else can I help you with?
From where do most of the cranial nerves originate?
Most of the cranial nerves originate from the brainstem.
Where do the cranial nerves exit?
The cranial nerves exit from the brainstem. They emerge from specific openings in the skull called foramina, which are small bony passageways. These openings provide a pathway for the cranial nerves to exit the skull and innervate different parts of the head and neck.
What is the difference between peripheral nerves and cranial nerves?
cranial nerves are nerves which arise from different parts of brain that are paired and 12 pair and 24 in number. peripheral nerves are neurons that exists out side brain and spinalcord and make up peripheral nerve system.
What part of the nervous system consists of all of the spinal nerves and cranial nerves is the?
The peripheral nervous system consists of all the spinal nerves and cranial nerves. These nerves connect the central nervous system (brain and spinal cord) to the rest of the body, allowing for communication and control of bodily functions.
What are the organs of smell and the cranial nerves connected to them?
The organ of smell is the nose - more specifically it is a patch of epithelium called the olfactory epithelium located in the roof of the nasal cavity. The cranial nerves associated with smell are the olfactory (I) nerves

What has the author A Brodal written?
A. Brodal has written: 'The cranial nerves' -- subject(s): Cranial Nerves
What is the total number of cranial nerves?
There are 12 pairs of cranial nerves, which make a total of 24 cranial nerves. These nerves emerge directly from the brain and are responsible for various sensory, motor, and autonomic functions in the head and neck.
