Muscles of the Pelvic Floor and Perineum01:26

Muscles of the Pelvic Floor and Perineum

4.8K
The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

Functions of Smooth Muscles01:23

Functions of Smooth Muscles

3.5K
Smooth muscles are an important type of muscle tissue that plays a vital role in the involuntary movements of internal organs. For example, they help regulate the movement of food through the gut and the flow of blood through the circulatory system.
Function of visceral smooth muscles
Visceral smooth muscle is found in the walls of all hollow organs, except the heart, and is a key player in the involuntary movements that drive the functioning of these internal organs. This tissue is arranged in...

Associative Learning01:27

Associative Learning

1.5K
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Association Areas of the Cortex01:21

Association Areas of the Cortex

9.5K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Genome-wide Association Studies-GWAS

15.8K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Somatosensory, Motor, and Association Cortex01:23

Somatosensory, Motor, and Association Cortex

2.8K
The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at...

Summary

Weak pelvic floor muscles and low vaginal resting pressure in early pregnancy are linked to preterm labor. Pelvic floor physical therapy may help prevent premature birth.

Area of Science:

  • Obstetrics and Gynecology
  • Pelvic Floor Physiology
  • Maternal-Fetal Medicine

Background:

  • The pelvic floor muscles support pelvic organs and play a role in labor, but their influence on labor duration is debated.
  • Weak pelvic floor muscles may contribute to cervical changes and preterm labor.

Purpose of the Study:

  • To measure vaginal resting pressure and pelvic floor muscle strength in the first trimester of pregnancy.
  • To investigate the association between these measures and the risk of preterm labor.

Main Methods:

  • A prospective study involving 320 low-risk pregnant women in their first trimester.
  • Assessment of pelvic floor muscle strength and vaginal resting pressure using a vaginal pressure measurement device.

Main Results:

  • Women who experienced preterm labor had significantly lower vaginal resting pressure and pelvic floor muscle strength.
  • Lower pelvic floor muscle strength (p=.01) and vaginal resting pressure (p=.009) were associated with preterm birth.

Conclusions:

  • Weak pelvic floor muscles and reduced vaginal resting pressure in early pregnancy are risk factors for spontaneous preterm labor.
  • Pelvic floor physical therapy could be a potential preventive strategy for reducing the incidence of preterm birth.
