Find the following structures:
- Opening of hair follicle on the skin of the nose
- Lobules of sebaceous glands in the nose
- Fat cells between the muscle fibers
- Chondrocytes in lacunae
- Keratinized squamous epithelium
- Cross and oblique section through a blood vessel
- Notice the orientation of the nuclei in the wall of the blood vessel. What is present inside the blood vessel?
- Sebaceous glands
- Skeletal muscle, fat cells and a small blood vessel is visible. Notice the nuclei just below the cell membrane of the skeletal muscle. Striations are also visible. A nucleus of endothelium is visible in the blood vessel.
- Identify the following:
- Skelet muscle with rows of nuclei.
- Perimysium.
- Perichondrium.
- Lacunae.
- Chondrocytes.
- How does perimysium differ from perichondrium?
- Hair follicle with associated glands.
- What is present between the glands? What type of gland is seen here? How does secretion take place?
- Notice the difference between the top and bottom of the structure. What is noticable?
- What type of epithelium is seen here?
- What is present in the middle of the nostril?
- How does the nostril differ from the epiglottis?
