Sex Linked Disorders01:43

Sex Linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
Couple01:29

Couple

A couple is a pair of parallel forces equal in magnitude but in opposite directions. The forces are separated by a perpendicular distance, known as the couple's arm. The couple causes a rotation force or moment that rotates the body about an axis perpendicular to the plane of the forces. The resulting moment is referred to as the couple moment. The SI unit of a couple moment is the Newton-meter (N-m).
A typical example to understand this concept is tightening a bolt with a lug wrench. A force...
Male Sexual Response: Erection & Ejaculation01:17

Male Sexual Response: Erection & Ejaculation

Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...
Sexually Transmitted Infections01:26

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
Psychosexual Stages of Personality: Genital01:23

Psychosexual Stages of Personality: Genital

The genital stage is the final phase of Sigmund Freud's theory of psychosexual development, beginning at puberty, around age 12. During this stage, sexual energy shifts from self-focused interests to external individuals, marking the development of mature adult sexuality. Freud saw this phase as a time of sexual reawakening, with desires directed toward others outside the family. A healthy transition into this stage, according to Freud, signifies the emergence of two key aspects of adult...
Couples Therapy01:26

Couples Therapy

Couples therapy is a therapeutic approach designed to help individuals in intimate relationships address conflicts, improve communication, and foster healthier dynamics. It is appropriate for couples at various stages, including those who are dating, married, or in long-term partnerships, and aims to support partners in navigating their unique relational challenges.
Core Principles and Techniques
Couples therapy often incorporates cognitive-behavioral principles to identify and modify negative...

Area of Science:

  • Neuroscience
  • Genetics
  • Behavioral Biology

Background:

  • Drosophila melanogaster serves as a model organism for studying genetically programmed behaviors.
  • Male courtship is a complex, innate behavior essential for reproduction.

Discussion:

  • The fruitless gene plays a critical role in regulating male courtship.
  • Specific neuronal circuits, particularly those involved in olfaction, are crucial for mediating courtship behavior.

Key Insights:

  • A single alternative splicing event of the fruitless transcript is essential for male courtship.
  • An olfactory-based neuronal circuit is directly implicated in the execution of courtship.

Outlook:

  • Further investigation into the fruitless gene's regulatory mechanisms can illuminate other complex behaviors.
  • Understanding these circuits can provide insights into the neural basis of innate behaviors across species.
