1-1 P.5 圖1-3 皮膚中的真皮，所含的結締組織是否應為「疏鬆」結締組織？

由以下資料可知人體皮膚中的真皮層(The dermis)中的結締組織，是屬於緻密結締組織(dense connective tissue)無誤。

 

資料一：

The dermis is also known as the corium (KOH-ree-um). It lies directly beneath the epidermis and is often referred to as the true skin. It is composed of dense connective tissue with tough white collagenous fibers and yellow elastin fibers. Blood vessels, nerves, lymph vessels, smooth muscles, sweat glands, hair follicles, and sebaceous glands are all embedded in the dermis.

資料三： 

Dermis consists primarily of dense connective tissue with stretchy elastin fibers and supportive collagen fibers. Blood vessels, lymph vessels, and sensory receptors weave through the dermis. Dermis is much thicker than epidermis, and more resistant to tearing. Leather is animal dermis that has been treated with chemical preservatives.
