Question

Two terms for the connective tissue below the dermis are _______. It is made of _______ and its functions include _______.

Answer 1

The connective tissue below the dermis is known as hypodermis or subcutaneous layer, comprised of loose connective and fatty tissues, with functions including fat storage, protection, cushioning, temperature regulation, and sensory perception.

Step-by-step explanation:

Two terms for the connective tissue below the dermis are hypodermis and subcutaneous layer. It is made of loose tissues that are connective and fatty and which include collagen and elastin fibers, allowing it to serve multiple functions. These functions include fat storage, protection, cushioning subcutaneous tissues, as well as playing a role in temperature regulation and sensory perception due to nerve endings that extend through the dermis.

Answer 2

The correct answer are: Hypodermis and subcutaneous layer; areolar and adipose tissue; stabilizing position of the skin.

Step-by-step explanation:

- The hypodermis, also called subcutaneous tissue, or superficial fascia, is the lowest layer of the integumentary system in vertebrates. The types of cells found in the hypodermis are fibroblasts, fat cells and macrophages. It derives from the mesoderm, but unlike the dermis, it does not derive from the dermatome in the region of the mesoderm. The hypodermis is mainly used to store fat.

- Areolar connective tissue: It is one of the most widely distributed. It contains cell types such as fibroblasts, macrophages, plasma cells, mast cells and white blood cells. It consists of collagen, elastic and reticular fibers. The main substances it contains are hyaluronic acid, chondroitin sulfate. This type of tissue is part of the subcutaneous tissue.

- Adipose tissue: It is composed of a cell type called adipocira that store triglycerides. It is associated with areolar tissue. It acts as an insulator to prevent heat loss. It is the main source of energy and provides support and protection to various organs.
