TERMS
A temporary acute paralysis or weakness of one side of the face.
What is Bell's Palsy
A naturally occurring barrier created by the modification of the brain capillaries that prevents many substances from leaving the blood and crossing the capillary walls into the brain tissue.
What is Blood-Brain Barrier
The pathway between the cerebral cortex and the spinal cord, and it controls many involuntary functions.
What is the Brainstem.
A blow causes acceleration-deceleration and rotational forces that may stretch, compress, or shear nerve fibers as the brain moves within the skull, and disrupts the brain chemicals responsible for brain function.
What is a Concusion
Rigid extension of all four extremities with hyperpronation of the forearms and plantar flexion of the feet.
What is Decerebrate Posturing
Contains nerves that enter and exit the spinal cord between the vertebrae, and also contains 12 pairs of cranial nerves that travel between the brain and organs without passing through the spinal cord and all of the body's other motor sensory nerves.
What is The Peripheral Nervous System
(1) Controls respiratory, circulatory, and vasomotor activities; houses respiratory center.
(2) Controls reflexes of swallowing, coughing, vomiting, sneezing, and hiccupping.
What is the Medulla Oblongata
The bacterial, viral, or fungal organism often colonizes in the upper respiratory tract, invades the bloodstream, and then crosses the blood-brain barrier to infect the cerebrospinal fluid and meninges.
The lateral wall of a somite from which the dermis is produced.
What is Dermatome
What is The Autonomic Nervous System
Conducts visual impulses from the eye to the brain. i.e. visual acuity and visual fields
What is the Optic Nerve (CN II)
Occurs when a thrombus or embolism interrupts the blood supply, oxygen, and nutrients to the brain, and brain cells die.
What is a Stroke
A disease marked by the inflammation of the meninges that is either a relatively mild illness caused by a virus, or a more severe life-threatening illness causes by a bacterium.
What is Meningitis
Contains the primary vision center and provides interpretation of visual data.
What is the Occipital Lobe
Supply motor and sensor fibers mostly in the face.
(1) Sensory - sensation to the cornea, iris, lacrimal glands, conjunctiva, eyelids, etc.
(2) Motor - jaw opening and clenching, chewing, mastication.
Trigeminal Nerve (CN V)
Causes include altered lipid metabolism, vitamin B12 or folate deficiency; it's also associated with Lyme disease, HIV infection, and diabetic polyneuropathy.
Peripheral Neuropathy
A sudden interruption of blood supply to a part of the brain or the rupture of a blood vessel, spilling blood into the spaces around the brain cells.
What is a Stroke
Contains the motor cortex associated with voluntary skeletal movement and fine repetitive motor movements, as well as the control of the eye movements.
What is the Frontal Lobe
Arise from the Medulla Oblongata and supplies chiefly the viscera especially with autonomic sensory and motor function.
(1) Sensory - sensation behind the ear and part of the external ear canal.
(2) Parasympathetic - secretion of digestive enzymes, peristalsis, carotid reflex, involuntary action of the heart, lungs, and digestive tract.
May be caused by an acute inflammation of the facial nerve (CN VII), such as a viral infection with herpes simplex which can lead to ischemia and demyelination.
