Difference Between Monera and Protista. The five-kingdom classification system divides the different life forms of earth into five distinct categories such as Kingdom Monera, Protists, Fungi, Plantae, and Animalia. Among them, Monera is the most primitive organism. The key difference between Monera and Protista is that Monera has a prokaryotic cellular organization, whereas Protista has … Read more
Difference Between Monera, Protista, Fungi, Animalia, Plantae. The five-kingdom classification was proposed by R.H. Whittaker in 1969 and was built on the work of two-kingdom classification. In Five Kingdom Classification, the organisms are classified based on several characteristics such as mode of nutrition, thallus organization, cell structure, phylogenetic relationships, and reproduction. It is the most … Read more
What is Viroid? Viroids represent the smallest known infectious agents affecting plants, characterized by a short (246–467 nt), circular, single-stranded RNA molecule. These entities are characterized by the absence of a protein coat or lipid envelope, categorizing them as “naked” RNA agents, which sets them apart from viruses. The RNA exhibits a robust, base-paired, rod-like … Read more
What is Muscle Cell? Definition of Muscle Cell A muscle cell, or myocyte, is a specialized animal cell designed for contraction, facilitated by organized motor proteins, primarily actin and myosin. These cells can be found in various forms, including skeletal, cardiac, and smooth muscle tissues, each serving distinct functions within the body. Structure of Muscle … Read more
Urinary casts are small, cylinder-shaped, tube-shaped particles that can be detected by a microscopic analysis of urine. Casts are the only kidney-specific components discovered in the urine sediment. It is believed that Tamm-Horsfall mucoprotein (uromodulin) released by renal tubular epithelial cells forms the fundamental matrix of all casts. Any components present in the tube filtrate, … Read more
The male reproductive system includes a number of hormones and organs that are involved in reproduction. These hormones and organs can be found either inside or outside of the pelvis. Organs of the Male Reproductive System External male reproductive structures: Internal male reproductive organs: External male reproductive structures The scrotum contains the testes, epididymides and … Read more
What is Ear? Definition of Ear The ear is a sensory organ responsible for hearing and maintaining balance in the body. It consists of the outer ear, middle ear, and inner ear, and it converts sound waves into electrical signals that can be interpreted by the brain. Anatomy of Ear – Structure of Ear The … Read more
What is Skeletal system? Definition of Skeletal system The skeletal system is the framework of bones, joints, and cartilages that provides support, protection, and facilitates movement in the human body. Types of Skeletal Systems There are three main types of skeletal systems found in different organisms: hydrostatic skeleton, exoskeleton, and endoskeleton. Each type of skeletal … Read more
What is skeletal muscle? Definition of skeletal muscle Skeletal muscle is a type of voluntary muscle tissue that is attached to the bones and responsible for movement and various bodily functions. Properties Of Skeletal Muscle Skeletal muscles possess several important properties that contribute to their function and enable them to perform various tasks: These properties … Read more
Muscle twitch, the brief and transient contraction of a muscle fiber, is a fundamental event in muscle physiology. Understanding the characteristics of muscle twitches provides insights into the intricate mechanisms that govern muscle function. This article delves into the key aspects of muscle twitch, focusing on motor units, summation, and tetanus. Muscle twitches are initiated … Read more
