Detailed Structure and Function of Lymph Nodes01:23

Detailed Structure and Function of Lymph Nodes

6.4K
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Cranial Nerves: Types Part II

6.0K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.
Facial Nerve (Cranial Nerve VII)
Cranial nerve VII, or the facial nerve,...

Secondary Lymphoid Organs01:15

Secondary Lymphoid Organs

10.3K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Anatomy of the Ear01:16

Anatomy of the Ear

13.8K
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...

Cranial Part of Parasympathetic Division01:18

Cranial Part of Parasympathetic Division

2.6K
The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.
The vagus nerve (cranial nerve X) alone accounts for approximately 75...

Lymphatic Vessels and Lymph Transport01:16

Lymphatic Vessels and Lymph Transport

24.7K
Lymphatic vessels, known as lymphatics, are crucial in transporting lymph from peripheral tissues to our venous system. This process begins with lymph entering through tiny capillaries that branch through tissues. These capillaries have unique features such as larger diameters, thinner walls, and a distinctive one-way valve system formed by overlapping endothelial cells.
This one-way system allows fluids, solutes, and even pathogens to enter but prevents their return to the intercellular...

Area of Science:

  • Medical Diagnostics
  • Pathology
  • Infectious Diseases

Background:

  • Hansen's disease (leprosy) elimination in India is challenged by low clinical suspicion.
  • Unusual presentations can lead to diagnostic delays.

Observation:

  • A patient presented with greater auricular nerve thickening, mimicking an enlarged neck lymph node.
  • Referred for fine needle aspiration cytology (FNAC).

Findings:

  • FNAC revealed epithelioid cell granulomas, suggestive of Hansen's disease.
  • Subsequent clinical examination and skin biopsy confirmed the diagnosis.

Implications:

  • Pathologists play a crucial role in identifying rare presentations of common diseases like Hansen's disease.
  • This case underscores the need for a high index of suspicion for leprosy, even with atypical symptoms.
