Study Notes
Sclera
- The sclera is the white, opaque, outermost fibrous coating of the eye.
- It provides structural support and protection for the inner components of the eye.
- The sclera covers most of the eyeball, except for the cornea, and is continuous with the cornea at the front of the eye.
- It is composed of dense connective tissue, primarily collagen, which makes it tough and resilient.
- The sclera also serves as an attachment point for the extraocular muscles, which control eye movement.
Ciliary Body
- The ciliary body is part of the eye's middle layer.
- It is responsible for producing aqueous humor.
- It contains the ciliary muscle, which controls the shape of the lens.
Iris
- The iris is the colored part of the eye that surrounds the pupil.
- It controls the amount of light entering the eye by adjusting the size of the pupil.
Choroid
- The choroid is the vascular layer of the eye, located between the sclera and the retina.
- It provides oxygen and nutrients to the outer layers of the retina.
Homologous Chromosomes
- Homologous chromosomes are pairs of chromosomes that have the same structure and size and carry genes for the same traits at corresponding positions (loci).
- In diploid organisms, one chromosome of each homologous pair is inherited from the mother and the other from the father.
- These chromosomes pair up during meiosis, the process of cell division that results in the formation of gametes (sperm and egg cells).
- Homologous chromosomes ensure the proper segregation of genetic material to offspring.
- Autosomes are non-sex chromosomes. Humans have 22 pairs of autosomes and one pair of sex chromosomes (XX or XY).
X-Chromosomes
- X-chromosomes are sex chromosomes that determine female sex characteristics in organisms with XY sex-determination systems.
- Females typically have two X-chromosomes.
Y-Chromosomes
- Y-chromosomes are sex chromosomes that determine male sex characteristics in organisms with XY sex-determination systems.
- Males typically have one X and one Y chromosome.
Ryder Cup
- The Ryder Cup is a biennial men's golf competition between teams from Europe and the United States.
- The event is named after the English businessman Samuel Ryder, who donated the trophy.
Ranji Trophy
- The Ranji Trophy is a domestic first-class cricket championship played in India.
