neuro part 1 SNS and diagnostic.txt

• sends information to tbe CNS from internal organs or from external stimuli
• sensations detected by receptors
• carried by sensory neurons from specialized organs to specific areas of the cerebral cortex

part of the frontal lobe

• carries info from CNS to organs, muscles and glands
• controls discrete skeletal muscle movement
• stimulation of right cortex produces muscle contractions on the left or contralateral side of body

controls coordinated muscle movement

involved in planning complex movements and in coordinating movements with both hands

• to obtain CSF for diagnostic procedures
• to treat disease by administering antibiotics or cancer agents into the spinal canal
• to administer local anesthetics
• to remove CSF for decreasing spinal fluid pressure

allows visualization of cerebral circulation by use of radiopaque materials

used for diagnosing pathological conditions such as tumors, hemorrhages, hematomas, hydrocephalus

radiographic process using contrast medium injected into lumbar subarachnoid space to view and photograph spinal cord and spinal subarachnoid space

records electrical activity of the brain (brain wave)

• noninvasive technique using a powerful magnetic field to align hydrogen atoms in water in the body
• provides much greater contrast between the different soft tissues of the body than CT scan

examines interior structure of the eye, including the lens, retina and optic nerve

measures the pressure inside the eye (intraocular pressure - IOP)

used to determine tone quality and/or hearing loss
