The last photo is the smooth muscle. Smooth muscle tissues are found on the intestinal wall. It generates tonic contractions that maintains the proportions of the organ when the stomach is loaded with foods and forceful contractions.

The second picture is the longitudinal section of hair root. It is where we can find the Matrix, Medulla, and Cortex. Also the surrounding epithelial and connective tissue sheaths.

The third one is the Sebaceous* gland. It secreted oil mixture of lipids called SEBUM. This oil helps in maintaining the stratum corneum and the hair shaft. It also has weak antibacterial and antifungal property.
