NMDA receptors (NMDARs) and AMPA receptors (AMPARs) in amygdala nuclei and the dorsal hippocampus (dHipp) are critical for fear conditioning. Enhancements in synaptic AMPAR expression in amygdala nuclei and the dHipp are critical for fear conditioning, with some studies observing changes in AMPAR expression across many neurons in these brain…

Urine formation in the nephron can be a very intimidating concept to students. This straightforward activity, performed by students during the nephron lecture, can help enforce the concepts as they uncover the structures and functions involved in urine formation.

Given the recently proposed three-filament theory of muscle contraction, we present a low-cost physical sarcomere model aimed at illustrating the role of titin in the production of active force in skeletal muscle. With inexpensive materials, it is possible to illustrate actin-myosin cross-bridge interactions between the thick and thin filaments…

This study investigates the goal-oriented nature of deceptive communication enacted through faking orgasms for people in diverse relationships that they perceived as less common or less accepted than more normative relationships (n = 501) using Multiple Goals Theory as a lens. Findings revealed that just over half the sample (52.4%) reported…

Undergraduate introductory human anatomy and human physiology courses are either taught as discipline-specific or integrated anatomy and physiology (A&P) sequences. An institution underwent a curricular revision to change the course approach from discipline-specific Human Anatomy and Human Physiology to an integrated A&P I and II sequence,…

The distribution of pulmonary blood flow is uneven and can be described as a three-zone model, the West zones: zone 1 occurs whenever alveolar pressure exceeds arterial pressure; zone 2 when the arterial pressure is greater than alveolar but the alveolar pressure exceeds the venous pressure; and finally zone 3 when both arterial and venous…

This research investigates the risk factors of poor sleep quality on cognitive performance among university students in Karachi, Pakistan. This study employed a quantitative survey-based approach. N= 202 participants between 18 to 25 years were selected through convenient sampling technique. Sleep Quality Scale (SQS) (Yi, et. al., 2006) was…

The multidisciplinary nature of physiology requires students to acquire, retain, apply, and evaluate knowledge from different scientific disciplines. Optimal learning techniques, such as active learning, interleaving topics and conditions, and recall, can greatly enhance the speed and effectiveness with which students achieve this type of…

The complexity of modern societies necessitates that children learn highly abstract material, such as mathematics, which often conflicts with behavioral goals that are innately motivating. For instance, children's educational success is generally evaluated based on their individual achievements, while humans are motivated to learn by engaging in…

Background: Research has established a bidirectional association between sleep disturbances and depression in both adults and youth, as well as links between depression and circadian rhythms and chronotype, predominantly in adult populations. However, the link between chronotype and depression in the general adolescent population, independently of…

The aim of this study was to investigate the effect of some sportive performance on the menstruation of female amateur volleyball players. 15 healthy female athletes with average age 20.0 ± 1.39 years, height average 165.93 ± 5.13 cm, body weight average 57.07 ± 4.42 kg and BMI (body mass index) 20.69 ± 4.78 kg/m2 , voluntarily participated in…

Climate change-related disasters have drawn increased attention to the impact of air pollution on health. 122 children ages 9-11 years old, M(SD) = 9.91(.56), participated. Levels of particulate matter (PM2.5) near participants' homes were obtained from the Environmental Protection Agency. Cytokines were assayed from 100 child serum samples: IL-6,…

This article will (1) initially outline first-year nursing and undergraduate exercise sciences student perspectives on examinations of the 2011 Michael-McFarland (M-M2011) core principles in physiology through an anonymous online survey, and (2) model an updated approach based on these qualitative findings. Briefly, for the first perspective (i of…

Impedance (Z), resistance (R), reactance (Xc), and phase angle (PhA) are sensitive to shifts in fluid between intra- and extracellular compartments, as would occur with nutrient uptake into skeletal muscle, but remains largely unexplored. To explore the sensitivity of whole-body and segmental (arms, legs, trunk) bioimpedance to acute feeding, 27…

The purpose of the study was to investigate velopharyngeal timing in children with and without speech sound disorders (SSDs) of unknown etiology. Six U.S. preschool-age children participated in the investigation. Three of the children had typically developing speech and language and three had SSDs of unknown etiology. Aerodynamic testing of the…
