Explain the histological structure of testis.

by

The testis, a vital male reproductive organ, has a simple structure with sperm-producing tubules and tissue between them. 1. Seminiferous Tubules: Key units for sperm production, supported by nourishing Sertoli cells. 2. Interstitial Tissue (Leydig Cells): Leydig cells, between tubules, produce testosterone for male reproductive functions. 3. Spermatogonia: Germ cells in tubules undergo mitosis to … Read more

Describe the structure of blastula.

by

1. Definition: It’s an early embryonic stage with a spherical arrangement of cells and a central fluid-filled cavity. 2. Formation: After the zygote’s intricate cell division in the morula stage, the blastula becomes a crucial milestone in development. 3. Hollow Structure:The blastula’s distinctive hollow nature with a fluid-filled cavity, the blastocoel, sets the stage for subsequent development. … Read more

Explain the histological structure of ovary in human.

by

The ovary has a central medulla and an outer cortex. The cortex is covered by germinal epithelium, while the medulla contains stroma with blood vessels, lymph vessels, and nerve fibers. In the cortex, you find developing ovarian follicles, starting with primordial follicles that have a central primary oocyte. Throughout the menstrual cycle, these primordial follicles … Read more

Describe the various methods of birth control to avoid pregnancy.

by

Birth control methods are categorized into temporary and permanent options: A. Temporary Methods: 1.Natural Method/Safe Period/Rhythm Method: Involves avoiding intercourse a week before and after menstrual bleeding, considering presumed ovulation on the 14th day of the menstrual cycle. 2.Coitus Interruptus or Withdrawal: Requires the male partner to withdraw before ejaculation to prevent insemination, acknowledging drawbacks due to … Read more

Which hormones are involved in parturition?

by

Parturition, the process of childbirth, involves a complex neuroendocrine mechanism: 1. Signals arise from the fully formed foetus and placenta cause mild uterine contractions. 2. This is accompanied by an increased estrogen-progesterone ratio and the rise of oxytocin receptors in uterine muscles. 3. The elevated hormone ratio leads to strong contractions of the uterus’s myometrium … Read more

Which as the function of male accessory glands?

by

Male accessory glands secrete substances that protect the gametes and facilitate their movement. 1. Seminal vesicles: These small pouches on the back of the urinary bladder release an alkaline fluid, making up around 60% of semen. This fluid, with fructose for energy, fibrinogen for coagulation, and prostaglandins for sperm movement, helps propel semen into the … Read more

What is capacitation? Give it’s importance.

by

Capacitation typically takes 5-6 hours, involving thinning of the acrosome membrane, entry of Ca++ into the sperm, and initiation of rapid whiplash movements in sperm tails. This process makes sperms highly active, prompting them to move upward from the vagina to the uterus and oviducts. Prostaglandins and female vestibular secretions further enhance sperm motility. Sperms … Read more

Describe female reproductive system of human.

by

The human female reproductive system consists of several important parts: i. Internal Genitalia: a. Ovary: The primary female sex organ, solid, oval, or almond-shaped, located near the kidneys. Measures 3 cm in length, 1.5 cm in breadth, and 1 cm in thickness. Positioned in the upper lateral part of the pelvis, held in place by … Read more
