Anatomy of the Brain: Ventricles01:18

Anatomy of the Brain: Ventricles

9.7K
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.

Development of Blood Vessels01:07

Development of Blood Vessels

1.6K
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

Development of the Heart01:27

Development of the Heart

3.1K
The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart...

Development of the Lymphatic System01:15

Development of the Lymphatic System

2.3K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

Neurulation01:30

Neurulation

46.6K
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...

Fetal Circulation01:14

Fetal Circulation

3.6K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Area of Science:

  • Neuroscience
  • Developmental Biology
  • Genetics

Background:

  • The brain ventricular system (BVS) is crucial for cerebrospinal fluid (CSF) circulation.
  • Disruptions in CSF flow are linked to neurodegenerative diseases like hydrocephalus and slit-ventricle syndrome.
  • Understanding BVS development is vital for addressing these conditions.

Purpose of the Study:

  • To review commonalities in zebrafish and vertebrate brain ventricular systems.
  • To highlight the utility of zebrafish as a model for BVS studies.
  • To explore novel genetic factors influencing BVS development and CSF circulation.

Main Methods:

  • Comparative analysis of zebrafish and vertebrate BVS morphology.
  • Review of recent functional genetics studies in zebrafish.
  • Examination of zebrafish mutants affecting potassium voltage-gated channels.

Main Results:

  • Zebrafish share conserved BVS elements with other vertebrates.
  • Novel genetic elements influencing BVS and CSF flow have been identified in zebrafish.
  • Studies on zebrafish mutants revealed functional convergence in protein transport essential for BVS development.

Conclusions:

  • Zebrafish are a valuable model for studying brain ventricular system development and related disorders.
  • Evolutionarily conserved protein transport mechanisms are essential for BVS formation.
  • Further research in zebrafish can elucidate the genetic underpinnings of hydrocephalus and slit-ventricle syndrome.
