CLASSIFICATION OF HUMAN HAIR

 Hair can be categorized in several ways based on its characteristics, such as texture, type, and growth patterns. Here’s an overview of the main types of hair:

1. By Texture

  • Straight Hair:

    • Characteristics: Lacks curl or wave; smooth and shiny.
    • Types: Can be fine, medium, or coarse.

  • Wavy Hair:

    • Characteristics: Forms a loose wave pattern; has a bit of texture.
    • Types: Ranges from soft waves to more defined waves.

  • Curly Hair:

    • Characteristics: Forms tight curls or ringlets; tends to be drier and more prone to frizz.
    • Types: Can be classified into several curl patterns (e.g., loose, medium, tight).

  • Coily/Kinky Hair:

    • Characteristics: Very tight curls or zigzag pattern; often very dense and fragile.
    • Types: Can vary in thickness and curl tightness.

2. By Thickness

  • Fine Hair:

    • Characteristics: Thin and soft; can appear limp and lacks volume.
    • Care: Needs lightweight products to avoid weighing it down.

  • Medium Hair:

    • Characteristics: A balance between fine and coarse; versatile and often healthy.
    • Care: Can handle a variety of products and styles.

  • Coarse Hair:

    • Characteristics: Thick and sturdy; often more resilient to styling.
    • Care: May require more moisturizing products to prevent dryness.

3. By Growth Patterns

  • Terminal Hair:

    • Characteristics: Thick, long, and pigmented hair found on the scalp, face, and body (e.g., eyebrows, eyelashes).
    • Development: Grows during puberty and is influenced by hormones.

  • Vellus Hair:

    • Characteristics: Fine, soft, and lightly pigmented hair often referred to as "peach fuzz."
    • Location: Covers most of the body and is usually shorter than terminal hair.

4. By Ethnicity

  • Asian Hair:

    • Characteristics: Generally straight and thick; tends to have a round cross-section.
    • Texture: Can be coarse but is often shiny and resilient.

  • Caucasian Hair:

    • Characteristics: Can be straight, wavy, or curly; varies widely in texture and color.
    • Diversity: Ranges from fine to coarse, with various cross-sectional shapes.

  • African Hair:

    • Characteristics: Typically coily or kinky; can be very dense.
    • Texture: Often dry and requires moisturizing products to maintain health.

Biochemistry plays in space exploration

  Biochemistry plays a critical role in space exploration by   helping to ensure the health and well-being of astronauts .   Space travel can have many negative effects on the human body, including: Bone and muscle loss Cardiovascular changes Weakened immune systems Hormonal imbalances Abnormal digestion and absorption Abnormal iron metabolism Ophthalmological issues   Biochemistry helps to develop strategies to counteract these effects. This includes:   Nutritional counter measures NASA's Nutritional & Biochemistry team develops and validates nutritional countermeasures to prevent or minimize the negative effects of spaceflight on the human body. For example, astronauts may need less iron during long-duration missions.   Understanding metabolic processes Understanding the impact of space travel on metabolic processes is vital for designing effective countermeasures.   Designing better equipment and technologies Understanding what happens...

Kidney function tests

  Kidney function tests  Kidney function tests are essential for assessing how well your kidneys are working.  1. Blood Tests: Serum Creatinine : Measures the level of creatinine, a waste product from muscle metabolism. Elevated levels may indicate impaired kidney function. Blood Urea Nitrogen (BUN) : Measures the amount of nitrogen in your blood from urea, another waste product. High levels can suggest kidney issues. Estimated Glomerular Filtration Rate (eGFR) : Calculated using serum creatinine, age, sex, and race. It estimates how well your kidneys are filtering blood. An eGFR below 60 may indicate kidney disease. 2. Urine Tests: Urinalysis : A dipstick test that checks for protein, blood, glucose, and other substances. Presence of protein (proteinuria) can indicate kidney damage. 24-Hour Urine Collection : Measures the total amount of waste products excreted in urine over 24 hours. This can help assess kidney function and detect kidney stones. 3. Imaging Tests: U...

Mpox

  Mpox(monkeypox) Mpox, previously known as monkeypox, is a viral illness caused by the monkeypox virus, a species of the genus  Orthopoxvirus . There are two distinct clades of the virus: clade I (with subclades Ia and Ib) and clade II (with subclades IIa and IIb). In 2022–2023 a global outbreak of mpox was caused by the clade IIb strain.  Mpox continues to be a threat today, and an upsurge of cases in the Democratic Republic of the Congo and other countries caused by clades Ia and Ib has raised concern. There are vaccines for mpox. Vaccination should be considered along with other public health interventions.  Common symptoms of mpox are a skin rash or mucosal lesions which can last 2–4 weeks accompanied by fever, headache, muscle aches, back pain, low energy and swollen lymph nodes.  Mpox can be transmitted through close contact with someone who has mpox, with contaminated materials, or with infected animals. During pregnancy, the virus may be passed to ...
