Insights

Rhinocerebral mucormycosis can spread to the brainstem via the trigeminal nerve, causing a pontine abscess. Magnetic resonance imaging (MRI) effectively visualized this rare perineural disease progression.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Medical Imaging

Background:

  • Rhinocerebral mucormycosis is a rare, aggressive fungal infection.
  • Involvement of the central nervous system is uncommon but serious.

Observation:

  • A case of rhinocerebral mucormycosis presented with an abscess in the lateral pons.
  • Perineural spread along the trigeminal nerve was identified as the likely pathway.

Findings:

  • Contrast-enhanced MRI demonstrated the extent of the fungal infection and perineural spread.
  • Pathological diagnosis was confirmed via rhino-orbital punch biopsy.

Implications:

  • Highlights the potential for unusual spread patterns in mucormycosis.
  • Emphasizes the utility of advanced imaging in diagnosing complex infections.
  • Underscores the importance of early recognition and biopsy for definitive diagnosis.

Spreading of Chromatin Modifications

The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

Spinal Nerves: Plexus II01:21

Spinal Nerves: Plexus II

The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Nerve Supply of the GI Tract

The neuronal supply to the gastrointestinal (GI) tract is essential for regulating various functions, including digestion, absorption, and movement of food. This intricate network of nerves is known as the enteric nervous system (ENS), often referred to as the "second brain" of the body.
The enteric nervous system consists of two major plexuses: the myenteric plexus (Auerbach's plexus) and the submucosal plexus (Meissner's plexus). These plexuses are located within the layers of...

Cranial Nerves: Types Part I

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, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

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.

Spinal Nerves: Anatomy

Spinal nerves are pivotal conduits in the nervous system, bridging the central nervous system (CNS) with the peripheral nervous system (PNS). These nerves enable a complex communication network between the brain, spinal cord, and the rest of the body, facilitating sensory input, motor output, and autonomic functions.
There are 31 bilateral pairs of spinal nerves, each emerging from the spinal cord through the intervertebral foramina—openings between adjacent vertebrae. These nerves are...
