The developmental process pertaining to the initial formation of an anatomical structure from unspecified parts. This process begins with the specific processes that contribute to the appearance of the discrete structure and ends when the structural rudiment is recognizable. An anatomical structure is any biological entity that occupies space and is distinguished from its surroundings. Anatomical structures can be macroscopic such as a carpel, or microscopic such as an acrosome. The process whose specific outcome is the progression of the epidermis over time, from its formation to the mature structure. The epidermis is the outer epithelial layer of a plant or animal, it may be a single layer that produces an extracellular material (e.g. the cuticle of arthropods) or a complex stratified squamous epithelium, as in the case of many vertebrate species. The process by which the anatomical structures of an ectodermal placode are generated and organized. Morphogenesis pertains to the creation of form. An ectodermal placode is a thickening of the ectoderm that is the primordium of many structures derived from the ectoderm. The developmental process by which a hair placode forms. An hair follicle placode is a thickening of the ectoderm that will give rise to the hair follicle bud. The process whose specific outcome is the progression of the hair follicle over time, from its formation to the mature structure. A hair follicle is a tube-like opening in the epidermis where the hair shaft develops and into which the sebaceous glands open. The developmental process by which an ectodermal placode forms. An ectodermal placode is a thickening of the ectoderm that is the primordium of many structures derived from the ectoderm. A multicellular organismal process involved in the cyclical phases of growth (anagen), regression (catagen), quiescence (telogen), and shedding (exogen) in the life of a hair; one of the collection or mass of filaments growing from the skin of an animal, and forming a covering for a part of the head or for any part or the whole of the body.
