Peripheral Nervous System: Ganglia and Nerves01:24

Peripheral Nervous System: Ganglia and Nerves

3.7K
The Peripheral Nervous System (PNS) is a crucial component of the body's neural network, extending beyond the central nervous system (CNS) to bridge the gap between the CNS and the external environment. It encompasses nerves, ganglia, and sensory receptors.
Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...

Nervous Tissue: Neuron Types

4.7K
Neurons, the fundamental units of the nervous system, can be classified based on both their structural and functional characteristics.
Structurally, neurons are categorized into three main types: multipolar, bipolar, and unipolar (or pseudounipolar). Multipolar neurons, which are the most common type in the brain and spinal cord, as well as all motor neurons, possess multiple dendrites and a single axon.
Bipolar neurons, on the other hand, have one primary dendrite and one axon. They are...

Blood and Nerve Supply to the Kidney01:18

Blood and Nerve Supply to the Kidney

2.9K
The kidneys are vital organs responsible for filtering and cleaning blood, removing waste products, and regulating electrolyte levels. To perform these essential functions, they require a constant and robust blood supply.
Bloody Supply to the Kidneys:
The kidneys receive their blood supply from the renal arteries, which branch off from the abdominal aorta—the main artery supplying the abdomen and lower body. The renal arteries enter the kidneys at the hilum, a notch on the medial side of...

Classification of Epithelial Tissues: Overview01:22

Classification of Epithelial Tissues: Overview

18.7K
Epithelial tissues are classified according to the shape of the cells and the number of cell layers formed. Cell shapes can be squamous (flattened and thin), cuboidal (square-like, as wide as it is tall), or columnar (rectangular, taller than it is wide). Additionally, the nucleus shape helps identify the type of epithelial cells. Squamous cells have flattened disc-shaped nuclei, cuboidal cells have spherical nuclei, and columnar cells have elongated nuclei.
Based on the number of cell layers,...

Organization of the Nervous System01:13

Organization of the Nervous System

8.5K
The nervous system is one of the most complex systems in our body. It is organized into two main divisions: the central nervous system (CNS) and the peripheral nervous system (PNS).
The CNS, comprising the brain and spinal cord, houses billions of neurons. The brain is housed in the skull, while the spinal cord is linked to the brain through the foramen magnum of the occipital bone and is surrounded by the protective structure of the vertebral column. It is responsible for processing various...

Neurulation01:30

Neurulation

43.7K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

    Area of Science:

    • Gynecologic Oncology
    • Neuro-oncology
    • Pathology

    Background:

    • Primitive neuroectodermal tumors (PNETs) are rare, aggressive ovarian neoplasms.
    • Fewer than 100 cases of ovarian PNETs have been documented.
    • PNETs of the ovary are classified into peripheral and central types.

    Observation:

    • Central type ovarian PNETs are classified based on morphological resemblance to central nervous system (CNS) tumors.
    • Peripheral PNETs exhibit small round cells, potentially with rosette formation.

    Findings:

    • This report details a rare case of a central type ovarian PNET.
    • The patient was a young female presenting with a pelvic mass.
    • Elevated serum tumor markers were noted in this patient.

    Implications:

    • This case underscores the importance of considering rare ovarian neoplasms in the differential diagnosis.
    • Increased awareness and further research into ovarian PNETs are crucial for improved patient outcomes.
    • Accurate classification and timely diagnosis are essential for managing aggressive ovarian tumors.
