NUR125 Lab- Module 6: ATI Engage Fundamentals: Sensory Perception

ATI Engage Fundamentals: Sensory Perception

Topics I learned and/or want to review;

An EMG, or electromyography, is performed to determine if there is damage to the nerves leading to the muscles. During an EMG, very small needles are inserted into a muscle. The needles are attached by a wire to an EMG machine that records the electrical activity in the muscle.

The Rinne test is performed when a tuning fork is struck and placed against the mastoid bone.

Myopia-Inability to see faraway objects clearly, also known as nearsightedness

Hyperopia-Inability to see nearby objects clearly, also known as farsightedness

Glaucoma-An increase in intraocular pressure compresses the optic nerve, causing a loss in peripheral vision

Presbyopia-Inability to see nearby objects clearly, often age-related

Tinnitus-Hearing sound when no external sound is present, such as ringing, buzzing, roaring, clicking, hissing, or humming noises

Sensorineural hearing loss-Hearing loss that occurs from problems either in the inner ear or on the vestibulocochlear(auditory) nerve(cranial nerve VIII)

The senses that can be impacted when taking specific medications.

NSAIDS- can affect hearing and taste

Antibiotics- can affect hearing, smell, and taste

Loop diuretics- can affect hearing

Antihypertensives- can affect taste

Psychotropics- can affect taste

Antihistamines(allergy relief)- can affect hearing, sight, smell, and taste

Aspirin- can affect hearing

Cranial Nerves cheat sheet;

“Some Say Marry Money, But My Brother Says Big Brains Matter Most”

This mnemonic for cranial nerves corresponds to the first letter of each nerve’s function in order:

  • Some: Sensory (olfactory – I)

  • Say: Sensory (optic – II)

  • Marry: Motor (oculomotor – III)

  • Money: Motor (trochlear – IV)

  • But: Both (trigeminal – V)

  • My: Motor (abducens – VI)

  • Brother: Both (facial – VII)

  • Says: Sensory (vestibulocochlear – VIII)

  • Big: Both (glossopharyngeal – IX)

  • Brains: Both (vagus – X)

  • Matter: Motor (spinal accessory – XI)

  • Most: Motor (hypoglossal – XII)
