CELL STRUCTURE AND ORGANISATION/ CLASS11 TH / WHAT IS CELL THEORY?
Просмотров 242 месяца назад
*What is a Cell? A cell is the structural and fundamental unit of life. The study of cells from its basic structure to the functions of every cell organelle is called Cell Biology. Robert Hooke was the first Biologist who discovered cells. Cells are complex and their components perform various functions in an organism. They are of different shapes and sizes, pretty much like bricks of the build...

Neuron as Structural and Functional Unit of Nervous tissue. Neuron is made up of three major parts- cell body, dendrite and axon. Cell body contains cytoplasm, cell organellNISSL’S granules. Short fibres projecting out from cell body is called dendrites. The axon is long fibre having branched structure at the end that terminates into knob like structure called Axon terminal which contain synpat...

Blood vessels, nerves and muscles, all have a loose connective tissue wrappings. The fib...
Embryonic Development Blastulation
Просмотров 303 месяца назад
2.6 Embryonic Development:- Embryonic development begins with the activation of the zygote, which undergoes cleavage, a series of early mitotic divisions without growth, forming a blastula composed of blastomeres. In humans, cleavage is holoblastic, meaning the entire zygote divides, with the first cleavage occurring around 30 hours after fertilization. Subsequent cleavages follow rapidly, incr...
Oogenesis and Fertilization
Просмотров 293 месяца назад
Oogenesis: Oogenesis is the process by which a haploid female gamete (egg or ovum) is formed from diploid germinal epithelium through mitosis and meiosis. It consists of three stages: 1. Multiplication Phase : Primary germinal cells (2n) undergo mitotic divisions to form oogonia (2n). This process is completed during the embryonic stage. 2. Growth Phase : Some oogonia enlarge to form primary oo...
WHAT IS MUSCULAR TISSUE (Animal Tissue)Class 11th
Просмотров 174 месяца назад
INTRODUCTION Muscular tissue is a specialized biological tissue that plays a key role in movement and support within the body. It is composed of cells known as muscle fibers, which have the unique ability to contract and relax. This contraction is primarily driven by the interaction between actin and myosin, two types of protein filaments within the muscle cells. Muscular tissue is classified i...
Spermatogenesis and Structure of sperm
Просмотров 184 месяца назад
2.4 Gametogenesis: The gametogenesis is the process of formation of gametes in sexually reproducing animals. The male gamete is sperm and the female gamete is ovum or egg. The gametes are formed from primordial germ cells of gonads. Spermatogenesis: Spermatogenesis is the formation of spermatozoa from the germinal epithelium of the testis, starting at puberty with the release of GnRH, which inc...
Puberty and Menstrual Cycle
Просмотров 394 месяца назад
- Puberty in Male and Female:- Puberty marks the functional maturity of the reproductive system, with males typically beginning between 12-15 years, driven by testosterone. In females, puberty starts with menarche at 10-14 years, leading to cyclic menstrual changes until menopause at 45-50 years. Menarche, menstrual cycles, and menopause are regulated by gonadotropic hormones. Menstrual Cycle:-...

INTRODUCTION WHAT IS EPITHELIAL TISSUE 1)simple epithelial - only having one layer of tissue 2) Stratified Epithelial - having more than 1 layer In Simple epithelial tissue is a type of tissue that lines the surfaces and cavities of structures throughout the body. It consists of a single layer of cells, which makes it ideal for functions such as absorption, secretion, and filtration. The cells ...

The vagina is a 7-9 cm tubular organ that serves as a copulatory organ, menstrual passage, and birth canal. Its walls consist of mucosal, muscular, and adventitial layers, with the mucosa storing glycogen. The external genitalia, collectively called the vulva, include the vestibule, labia minora, clitoris, labia majora, and mons pubis. Bartholin's glands secrete lubricating fluid. Mammary gland...

INTRODUCTION The endoplasmic reticulum (ER) is an essential organelle in eukaryotic cells, involved in the synthesis, folding, modification, and transport of proteins and lipids. It consists of a network of membranous tubules and sacs, called cisternae. There are two types of ER: 1. Rough Endoplasmic Reticulum (RER) : - Structure : Studded with ribosomes on its cytoplasmic surface, giving it a ...

Credited:- @SciencePhotoLibrary Ovarian histology of a mature female :- In the mature ovary, cyclic changes occur during each menstrual cycle involving the maturation of primordial follicles into primary, secondary, and Graafian follicles. Primary follicles have multilayered cuboidal follicular cells, which then develop the theca layer to become secondary follicles. These follicles grow, with g...
