Osmoregulation in Fishes02:32

Osmoregulation in Fishes

50.0K
When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

Internal Receptors01:31

Internal Receptors

70.4K
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

Background and Environment Affect Phenotype

6.6K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Types of Receptors: Internal Receptors

25.6K
Many cellular signals are hydrophilic and cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind intracellular receptors that reside within the cell cytoplasm or nucleus. Many mammalian steroid hormones and nitric oxide (NO) gas use this cell signaling mechanism.
Similar to membrane-bound receptors, the binding of a ligand to the intracellular receptor of causes a conformational change in the...

Regulation of Hormone Secretion01:19

Regulation of Hormone Secretion

3.6K
Regulation of hormone secretion is a finely tuned orchestration driven by various types of stimuli, encompassing neural, humoral, and hormonal signals. Environmental cues instigate neural stimuli, where action potentials traverse nerve fibers to reach their designated targets. An illustrative scenario is the body's response to stress, wherein the sympathetic nervous system releases epinephrine from the adrenal glands, inducing the well-known 'fight or flight' reaction.
Humoral...

Fixed Action Patterns01:06

Fixed Action Patterns

16.1K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Area of Science:

  • Animal behavior
  • Neuroscience
  • Endocrinology

Background:

  • Pheromones are vital chemical signals mediating animal communication, particularly for reproduction and social interactions.
  • Understanding pheromone ligands and olfactory receptors is key to deciphering sensory processing of these cues.
  • Behavioral responses to pheromones are dynamic and influenced by an individual's physiological state.

Approach:

  • This review outlines mechanisms of pheromone sensation.
  • It highlights physiological regulators, focusing on hormonal influences on pheromone-guided behaviors.
  • The review examines hormonal regulation across vertebrates, including fish, amphibians, and rodents.

Key Points:

  • Hormones play a crucial role in modulating pheromonal communication.
  • Regulation of pheromonal communication by hormones can occur in both peripheral olfactory organs and the brain.
  • The precise mechanisms by which hormones influence pheromone sensation and behavior require further elucidation.

Conclusions:

  • Hormonal mechanisms are central to regulating pheromone-guided behaviors across diverse vertebrate taxa.
  • Further research is needed to fully understand the neuroendocrine pathways involved in pheromone processing.
  • Comparative studies across species, particularly focusing on fish, offer valuable insights into conserved hormonal regulatory functions.
