Image: ear of a mouse. Many structures and tissues can be observed. Gomori's trichrome staining.

Epidermis: it is keratinized stratified squamous epithelium that forms the outer layer of the skin.

Dermis: it is dense irregular connective tissue that forms the layer immediately below the epidermis. Dermis and epidermis, together with hypodermis, form the skin.

Hair follicle: it is the skin structure of mammals where hair is formed.

Hypodermis: it is the deeper layer of the skin, just below the dermis. Hypodermis is mostly made up of adipocytes.

Skeletal muscle: it is formed of skeletal striated muscle cells. The contraction of this muscle cells drive the ear movements.

Elastic cartilage: it is the type of cartilage found in the ear and nose. Elastic cartilage provides mechanical support and elasticity to the ear.

Nerves: are bundles of axons that innervate the ear tissues, mostly the skeletal muscle cells, but also bring out sensory information from the ear to the encephalon.

Adipose tissue: it is the tissue specialized in storing lipids as energy source.

Conective tissue: it is the tissue that forms part of many organs and structures.

Blood vessels: each organ of the body is irrigated by a dense network of blood vessels. Commonly, they can be found in pairs: artery and vein.
