Olfactory Receptors: Location and Structure01:03

Olfactory Receptors: Location and Structure

12.4K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Olfaction01:25

Olfaction

49.2K
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.
The olfactory receptors are embedded in the cilia of the...

Physiology of Smell and Olfactory Pathway

13.4K
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.

Assessment of the Mouth01:26

Assessment of the Mouth

1.3K
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Psychosexual Stages of Personality: Oral01:16

Psychosexual Stages of Personality: Oral

3.4K
The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.
Weaning, typically occurring...

Taste Buds and Receptors01:20

Taste Buds and Receptors

5.6K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Area of Science:

  • Neurology
  • Neuroimaging
  • Stroke Medicine

Background:

  • Cheiro-oral syndrome is a rare neurological condition.
  • It typically presents with sensory disturbances in the face and hand.

Observation:

  • A 64-year-old man experienced left-sided facial and hand numbness for two days.
  • Physical examination confirmed reduced sensation in the left mouth corner and ipsilateral fingers.

Findings:

  • Neuroimaging revealed an acute lacunar infarct in the right thalamus.
  • This finding confirmed the diagnosis of cheiro-oral syndrome.

Implications:

  • Early diagnosis of cheiro-oral syndrome is vital.
  • Appropriate management can help prevent recurrent cerebrovascular events.
  • This case highlights the importance of recognizing thalamic infarct presentations.
