Spinal Cord: Gross Anatomy

7.5K
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...

Arc Length of a Curve: Problem Solving

173
A high-voltage power line spans a 40-meter horizontal distance between two transmission towers, resulting in a 10-meter vertical sag due to the effects of gravity and thermal expansion. The curve formed by the suspended cable is a catenary, which accurately models the behavior of a uniform, flexible cable under its own weight. Unlike a parabolic shape, the catenary is described by the hyperbolic cosine function and offers a precise representation of the cable's form.In this setup, engineers...

Muscles that Move the Head

7.2K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Spinal Cord: Cross-sectional Anatomy

6.4K
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...

Summary
This summary is machine-generated.

Transvaginal ultrasound cervical length screening effectively predicts preterm birth risk in asymptomatic singleton pregnancies. Early screening and intervention with vaginal progesterone can reduce preterm birth rates.

Area of Science:

  • Obstetrics and Gynecology
  • Maternal-Fetal Medicine
  • Neonatal Health

Background:

  • Preterm birth (PTB) remains a primary cause of infant illness and death.
  • PTB rates have seen a modest decline, reaching 11.4% in 2013.
  • Transvaginal ultrasound (TVU) cervical length (CL) measurement is a key predictor of PTB.

Purpose of the Study:

  • To outline current guidelines for TVU CL screening in predicting PTB.
  • To define appropriate interventions based on CL measurements.
  • To clarify screening recommendations across different pregnancy types and symptoms.

Main Methods:

  • Utilizing TVU to measure cervical length (CL) in various obstetric scenarios.
  • Implementing vaginal progesterone for short cervices (≤20 mm) in specific populations.
  • Serial CL screening for women with a history of spontaneous PTB.
  • Fetal fibronectin testing for symptomatic women in preterm labor.

Main Results:

  • TVU CL screening is recommended for asymptomatic singletons without prior PTB.
  • Vaginal progesterone is indicated for asymptomatic singletons with CL ≤20 mm.
  • Serial screening is advised for asymptomatic singletons with prior spontaneous PTB.
  • Routine cervical screening is not recommended for multiple gestations.
  • TVU CL screening and fetal fibronectin testing are recommended for symptomatic women.

Conclusions:

  • TVU CL screening is a valuable tool for predicting PTB in select asymptomatic pregnancies.
  • Targeted interventions, like vaginal progesterone, can mitigate PTB risk.
  • Screening protocols should be tailored based on individual risk factors and pregnancy status.
