external lamina的意思|示意

'

External lamina is an anatomical term of the vertebrate body that refers to the outermost layer of tissue in the body. It is a membrane that covers the body and also separates different organs and tissues.

As an external, protective layer, the external lamina helps to keep the body temperature steady, supports the body, and helps protect it from injury and disease. It is made up of a combination of proteins and lipids which allows it to perform its function properly. Additionally, the external lamina helps to maintain the body’s shape and structure.

The external lamina is composed of several layers. The outermost layer is the epidermis, which is the layer of skin that we interact with every day. Underneath this is the dermis, which is the supportive layer that houses our sweat glands and hair follicles. The deepest layer of the external lamina is the hypodermis, which is the layer of fat and connective tissue that provides insulation for the body and helps to protect internal organs.

The external lamina serves an important role in the body, as it helps to protect against disease, injury, and environmental factors. Additionally, it helps to keep the body at a steady temperature, support the body, and hold it together.
