Arteries of the Head and Neck01:26

Arteries of the Head and Neck

2.0K
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Cranial and Spinal Meninges01:19

Cranial and Spinal Meninges

2.2K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

The Arch of Aorta01:10

The Arch of Aorta

1.1K
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

Vertebral Column: Regions and Curvature01:16

Vertebral Column: Regions and Curvature

4.9K
The vertebral column or spine is a flexible column that supports the head, neck, and body and  allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

Spinal Cord: Cross-sectional Anatomy

2.8K
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.
Gray Matter and its Components
Central to the gray matter is...

Spinal Cord: Gross Anatomy01:15

Spinal Cord: Gross Anatomy

4.1K
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...

    Area of Science:

    • Neurology
    • Pediatric Neurosurgery
    • Developmental Biology

    Background:

    • Arnold-Chiari malformation (ACM) is the most complex of four Chiari malformation types, characterized by hindbrain displacement.
    • Approximately 95% of infants with ACM also have myelomeningocele (MMC), the most severe form of spina bifida.
    • Symptomatic comorbidities significantly increase morbidity and mortality risk in affected infants.

    Purpose of the Study:

    • To emphasize the critical need for prompt identification and diagnosis of ACM.
    • To highlight the importance of evidence-based medical and nursing care for ACM and associated MMC.
    • To underscore the benefits of early surgical intervention for ACM and MMC.

    Main Methods:

    • Review of clinical characteristics and outcomes associated with Arnold-Chiari malformation.
    • Analysis of the impact of comorbidities on infant morbidity and mortality.
    • Evaluation of the role of early surgical repair and postnatal care.

    Main Results:

    • ACM involves hindbrain herniation through the foramen magnum.
    • ACM is frequently associated with myelomeningocele in infants.
    • Early intervention improves patient outcomes and reduces healthcare burden.

    Conclusions:

    • Prompt diagnosis and evidence-based care are essential for infants with ACM and MMC.
    • Early surgical intervention can significantly improve quality of life and reduce disease burden.
    • Multidisciplinary care is critical for managing this complex congenital condition.
