    Parietal Lobe

    The human brain, a marvel of nature’s engineering, is segmented into different lobes, each with its unique responsibility. The parietal lobe, situated at the upper back part of the cortex, is crucial for sensory integration. It interprets signals from the body, including touch, temperature, and taste, aiding in spatial awareness and coordination.


    Commonly known as the kneecap, the patella is a triangular bone located at the front of the knee joint. It protects the knee and provides leverage to the quadriceps muscles, facilitating leg extension.


    Extending the hands and feet are the phalanges – the bones of the fingers and toes. Each hand and foot possesses 14 phalanges, divided as three for each finger and toe, except for the thumb and big toe, which have two each. These bones provide dexterity and aid in tactile sensation.

    Pineal Gland

    Tucked within the brain’s depths is the pineal gland, a tiny, pinecone-shaped endocrine organ. It’s most known for secreting melatonin, a hormone responsible for regulating sleep-wake cycles.

    Pituitary Gland

    Often referred to as the “master gland,” the pituitary is a pea-sized organ located at the base of the brain. It plays a central role in the endocrine system, producing a variety of hormones that govern other glands and influence numerous body functions, from growth and reproduction to metabolism.


    Blood, the life-sustaining fluid coursing through our veins, is composed of various components. Plasma is the liquid portion, making up about 55% of total blood volume. It carries cells, nutrients, hormones, and waste products throughout the body.

    Enveloping the lungs are two thin membranes called the pleura. They provide lubrication and facilitate the smooth expansion and contraction of the lungs during breathing.


    Exclusive to males, the prostate is a walnut-sized gland located beneath the bladder. It secretes a fluid that nourishes and protects sperm, playing a crucial role in the male reproductive system.


    Central to the human eye’s anatomy is the pupil, the black, circular opening in the middle of the iris. It regulates the amount of light entering the eye, contracting in bright conditions and dilating in dimmer settings to optimize vision.


    The heart, our rhythmic life pump, is encased in a double-walled sac called the pericardium. It provides protection, lubrication, and anchorage to the heart, ensuring its efficient function.
