Anatomy of the Ear

Anatomy of the Ear

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...

Hearing

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.

The Auditory Ossicles

The Auditory Ossicles

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...

Epistaxis

Epistaxis

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Signs of Puberty

Signs of Puberty

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Echo

Echo

The human ear cannot distinguish between two sources of sound if they happen to reach within a specific time interval, typically 0.1 seconds apart. More than this, and they are perceived as separate sources.
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case,...

Area of Science:

Dermatology
Pediatrics
Photobiology

Background:

Juvenile spring eruption (JSE) is a benign, self-limiting skin reaction.
It typically affects boys aged 4-12 years with exposed earlobes.
The condition is triggered by sunlight, particularly on sunny spring days.

Purpose of the Study:

To describe a case of juvenile spring eruption in a previously healthy boy.
To outline the clinical presentation and management of JSE.
To emphasize the importance of sun protection for recurrent cases.

Main Methods:

Clinical observation and physical examination of the patient.
Diagnosis based on characteristic symptoms and patient demographics.
Treatment with topical corticosteroids and oral antihistamines.

Main Results:

The patient presented with bilateral ear swelling, redness, and blisters.
Symptoms were consistent with juvenile spring eruption.
Treatment led to a reduction in swelling and discomfort.

Conclusions:

Juvenile spring eruption is a common reaction to sunlight in susceptible children.
Prompt symptomatic treatment can alleviate discomfort.
Preventative measures, including sunscreen and hats, are recommended for recurrence.
