Physiological Barriers01:25

Physiological Barriers

5.1K
Physiological barriers are semi-permeable cellular structures restricting drug diffusion into intracellular compartments and tissues. There are six types of physiological barriers: blood endothelial, cell membrane, blood-brain, blood-cerebrospinal fluid (CSF), blood-placenta, and blood-testis barriers.
The blood endothelial barrier is the most porous of these. It allows all small ionized, un-ionized, and lipophilic molecules to pass through the endothelial lining into the interstitial space...

Liver Physiology01:30

Liver Physiology

3.6K
The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of  70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...

The Physiology of Taste01:24

The Physiology of Taste

7.3K
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the...

Physiology of Emotion01:20

Physiology of Emotion

3.2K
The physiology of emotions is a multifaceted process involving the autonomic nervous system, brain structures, hormones, and neurotransmitters. This intricate interplay dictates how emotions manifest in the body and influence behavior.
Autonomic Nervous System
The autonomic nervous system (ANS) plays a critical role in emotional responses by regulating involuntary physiological functions. It consists of two main components: the sympathetic and parasympathetic systems. The sympathetic system...

Physiology of Urine Formation01:24

Physiology of Urine Formation

12.3K
Urine formation is an essential function of the human body. It plays a critical role in maintaining homeostasis by regulating the volume and composition of body fluids. The kidneys, the primary organs involved in this process, filter blood to remove waste products and excess substances, ultimately producing urine.
Glomerular Filtration
The first stage in urine formation is glomerular filtration. Each kidney contains approximately 1 million nephrons, the functional units of filtration, with a...

Overview of Anatomy and Physiology01:24

Overview of Anatomy and Physiology

35.2K
Human anatomy is the scientific study of the body's structures. Some of these structures are very small and can only be observed and analyzed with the assistance of a microscope. Other larger structures can readily be seen, manipulated, measured, and weighed. The word "anatomy" comes from a Greek root that means "to cut apart." Human anatomy was first studied by observing the body's exterior and the wounds of soldiers and other injuries. Later, physicians were allowed to...

Area of Science:

  • Affective Neuroscience
  • Psychophysiology
  • Embodied Cognition

Background:

  • The James-Lange theory proposed that physiological responses to stimuli cause subjective emotion.
  • Contemporary models integrate central nervous system (CNS) processing with peripheral signals for emotion generation.
  • The concept of 'feelings' encompasses perceptions of bodily changes, whether real or simulated.

Purpose of the Study:

  • To examine the multifaceted role of peripheral physiology in emotional experience.
  • To synthesize historical and modern perspectives on emotion and bodily states.
  • To explore the neural and developmental underpinnings of physiological feelings.

Main Methods:

  • Literature review integrating historical theories, neuroanatomy, physiology, and developmental psychology.
  • Analysis of interoception as the brain's processing of somatic signals.
  • Examination of diverse physiological systems contributing to emotional feelings.

Main Results:

  • Emotion is viewed as an interactive network of "bottom-up" (peripheral) and "top-down" (central) signaling.
  • Interoception, the brain's representation of bodily states, is crucial for subjective feelings.
  • Physiological feelings originate from various systems, including the PNS, endocrine, immune, and gastrointestinal tracts.

Conclusions:

  • Peripheral physiological signals are integral to the subjective experience of emotion.
  • Understanding interoception provides insight into the generation of feelings.
  • A comprehensive view requires integrating physiological, neural, developmental, and linguistic perspectives on emotion.
