What is the structure of the human ear?
A brief description of the human ear along with a well-labelled diagram is given below for reference. Pinna/auricle is the outermost section of the ear. The external auditory canal links the exterior ear to the inner or the middle ear. The tympanic membrane, also known as the eardrum, separates the outer ear from the inner ear.
How are gametes formed in animals?
The gametes in animals, including human beings, are formed from germ cells in the embryo. The germ cells are collectively referred to as the germ line, consisting of cells that will or can become the future gametes.
What is the function of gametes?
Gametes are the haploid cells that form a diploid cell called a zygote after fertilization. Zygote forms the first stage in the development of a unique entity and thus helps in the continuation of generations.
What are the facts of gametogenesis?
Q.1. What are the facts of Gametogenesis? Ans: Gametogenesis refers to the formation of gametes. It includes spermatogenesis that refers to the formation of sperms or male gametes in testes and oogenesis refers to the formation of ova in the ovaries.
What is the function of the ear canal?
The ear canal functions as an entryway for sound waves, which get propelled toward the tympanic membrane, known as the eardrum. When sounds enter the middle ear, they are transmitted to tiny bones called the ossicles, which consist of the stapes, the incus, and the malleus.
What is the function of the eardrum?
Eardrum is a biological membrane that separates the outer ear from the middle ear. Eardrum is composed of connective tissues covered with skin outside and with the mucous membrane inside.
What is the function of outer outer and middle ear?
Outer ear: It consists of a pinna and auditory canal that collects the sound waves and sends them to the eardrum. Middle ear: It consists of three ossicles (i.e., malleus, incus, and stapes) that increase the efficiency of sound transmission by increasing their amplitude.
