The subglottis or subglottic region is the lower portion of the larynx, extending from just beneath the vocal cords down to the top of the trachea. The structures in the subglottis are implicated in the regulation of the temperature of the breath.
The subcutaneous tissue (from Latin subcutaneous, meaning beneath the skin), also called the hypodermis, hypoderm (from Greek, meaning beneath the skin), subcutis, or superficial fascia, is the lowermost layer of the integumentary system in vertebrates.he types of cells found in the hypodermis are fibroblasts, adipose cells, and macrophages. The hypodermis is derived from the mesoderm, but unlike the dermis, it is not derived from the dermatome region of the mesoderm. In arthropods, the hypodermis is an epidermal layer of cells that secretes the chitinous cuticle.
