Anatomy of the Ear01:16

Anatomy of the Ear

9.1K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

The Auditory Ossicles01:11

The Auditory Ossicles

2.2K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

Assessing Body Temperature - Tympanic membrane

741
Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

Therapeutic Communication01:30

Therapeutic Communication

5.8K
Communication is a lifelong learning process. Through therapeutic communication, nurses can collect relevant assessment data, provide education and counseling, and interact during nursing interventions. Sending and receiving messages occur through verbal and nonverbal communication techniques and can happen separately or simultaneously.
Verbal communication depends on language or a prescribed way of using words so that people can share information effectively. The critical aspects of verbal...

Sign Convention01:30

Sign Convention

2.7K
When analyzing a beam subjected to various loads, it is crucial to understand the internal forces and moments generated within the structure. These internal forces can be broadly classified into normal forces, shear forces, and bending moments. To determine these forces and moments, we use the method of sections and apply a specific sign convention based on their direction and the side of the section being analyzed.
The normal force acts perpendicular to the beam's cross-section and can...

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Area of Science:

  • Cardiology
  • Clinical Signs

Background:

  • Tricuspid regurgitation is a heart valve disorder where the valve between the right atrium and ventricle does not close properly.
  • Clinical examination plays a vital role in diagnosing cardiac conditions.

Purpose of the Study:

  • To describe the winking earlobe sign as a potential clinical indicator of tricuspid regurgitation.
  • To highlight novel physical examination findings in cardiology.

Main Methods:

  • Observational study involving patients with suspected or confirmed tricuspid regurgitation.
  • Clinical assessment focusing on physical signs, including earlobe movement synchronous with pulse.

Main Results:

  • The winking earlobe sign, characterized by visible earlobe pulsation, was identified as a sign associated with tricuspid regurgitation.
  • This sign correlates with the pulsatile flow caused by the backward leakage of blood through the tricuspid valve.

Conclusions:

  • The winking earlobe sign is a novel, observable physical manifestation of tricuspid regurgitation.
  • This sign may serve as a simple bedside indicator, prompting further investigation for tricuspid regurgitation.
