Summary
This study quantifies guinea pig spinal cord development, revealing white matter volume doubles gray matter
Area of Science:
- Neuroscience
- Developmental Biology
- Comparative Anatomy
Background:
- Understanding spinal cord development is crucial for neuroscience.
- Morphometric analysis provides quantitative insights into tissue changes.
Purpose of the Study:
- To determine volumetric changes in white and gray matter of the guinea pig spinal cord during development.
- To compare the growth patterns of white and gray matter.
Main Methods:
- Utilized an image analysis system for morphometric study.
- Measured white and gray matter volumes in 10-microgram spinal cord sections.
- Analyzed samples from 1-day-old and 90-day-old guinea pigs.
Main Results:
- Observed topographic correspondences in volumetric values between young and adult guinea pigs, more pronounced in white matter.
- White matter volume increased twofold compared to gray matter during development.
- Quantified significant developmental changes in guinea pig spinal cord composition.
Conclusions:
- Guinea pig spinal cord development involves differential growth of white and gray matter.
- Morphometric analysis is effective for studying developmental changes in neural tissues.
- Findings contribute to the understanding of neurodevelopmental processes.

01:54The Spinal Cord
31.9K
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

01:10Spinal Cord: Information Processing
3.6K
The spinal cord is an integral hub for motor and sensory information that enables the brain to communicate with the peripheral nervous system (PNS). This communication consists of relaying sensory data and transmission of motor commands.
Sensory Information Processing
Sensory information processing begins at the sensory receptors located in the skin and other tissues, which detect somatic sensory stimuli such as touch, temperature, or pain. These receptors function as catalysts, initiating...

01:16Spinal Cord: Cross-sectional Anatomy
4.9K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

5.9K
The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...

The spinal cord, a critical component of the central nervous system, extends from the base of the brainstem to the lumbar region of the vertebral column. It is essential for maintaining physical stability and facilitating communication between the brain and peripheral parts of the body.
