Muscles of the Eye01:20

Muscles of the Eye

4.2K
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...

Accessory Structures of the Eye

3.6K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

5.8K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Ethics in Research

25.6K
Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

Attribution Theory00:56

Attribution Theory

13.8K
Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).

Group Polarization01:01

Group Polarization

39.2K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Area of Science:

  • Oncology
  • Pathology
  • Otorhinolaryngology

Background:

  • Hybrid tumours, defined as neoplasms composed of at least two distinct histological tumour types originating from the same topographical area, are exceptionally rare.
  • Maxillary sinus tumours can present with non-specific symptoms like nasal congestion and epiphora, potentially masking aggressive underlying pathology.

Observation:

  • A 51-year-old male presented with a 6-week history of nasal congestion and epiphora, leading to the discovery of a maxillary sinus tumour with extensive local invasion.
  • Radiological imaging confirmed the presence of the tumour, necessitating aggressive surgical intervention.

Findings:

  • Histopathological examination of the excised specimen revealed a rare hybrid tumour comprising adenoid cystic carcinoma, salivary duct carcinoma, epithelial-myoepithelial carcinoma, and basal cell adenoma.
  • The distinct tumour components were not separated, indicating a single origin within the maxillary sinus.

Implications:

  • The diagnosis and management of hybrid tumours require a high index of suspicion and meticulous pathological evaluation to identify all components, especially more aggressive ones.
  • Treatment should be guided by the highest-grade tumour component, emphasizing the need for comprehensive oncological care.
