Secondary Active Transport01:55

Secondary Active Transport

138.1K
One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

Secondary Healthcare System

2.1K
Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident. Whatever...

Primary and Secondary Growth in Roots and Shoots

60.7K
Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Secondary Distribution01:25

Secondary Distribution

583
Secondary distribution systems provide electrical energy at the utilization voltage levels from distribution transformers to customer meters. Typical secondary voltages in the United States include 120/240 V for residential use, 208Y/120 V for residential and commercial use, and 480Y/277 V for industrial and high-rise commercial use.
In residential areas, 120/240 V single-phase, three-wire service is commonly used for lighting, outlets, and large appliances. Urban areas with high-density loads...

Secondary Lymphoid Organs01:15

Secondary Lymphoid Organs

9.6K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Area of Science:

  • Pediatric Urology
  • Congenital Abnormalities

Background:

  • Megaprepuce is a rare congenital penile anomaly characterized by an abnormally large foreskin.
  • Understanding its etiology and clinical presentation is crucial for appropriate management.

Observation:

  • A 3-month-old male infant presented with a congenital megaprepuce.
  • The condition was noted from birth, prompting further investigation.

Findings:

  • This case highlights the diagnostic and therapeutic considerations for megaprepuce.
  • A review of the literature identified only three unique previously reported cases.

Implications:

  • This report contributes to the limited understanding of megaprepuce.
  • Further research may elucidate optimal treatment strategies for this rare condition.
