Tissues

Other than intervertebral disc all are hyaline cartilage

Most tissues undergo cell turnover with slow cell division and cell death. Nerve tissue and cardiac muscle are exceptions because their differentiated cells cannot undergo mitosis.

-Nucleus is situated at the periphery in case of yellow fat.
-Yellow fat is unilocular. Brown fat is multilocular.

Capillaries have only an endothelium, with no subendothelial layer or other tunics.

Lamina propria is a loose connective tissue

Capillaries have only an endothelium, with no subendothelial layer or other tunics.

Classification of glands based on nature of secretion:
1. Mucous glands- Secrete thick mucoid secretion called mucin.
Example: Goblet cells, sublingual salivary glands

2. Serous glands- Secrete a protein rich watery secretion.
Example: Exocrine pancreas, parotid glands, lacrimal gland, von Ebnar's gland in tongue.

3. Mixed glands- Which contain both mucous and serous cells and produce sero-mucous
secretion. Example: Submandibular salivary gland.

Trachea is lined by Ciliated pseudostratified columnar epithelium

Foetal skeleton is a hyaline cartilage

Unique transitional epithelium or urothelium lines much of the urinary tract, extending from the kidneys to the proximal part of the urethra, and is characterized by a superficial layer of large, dome-like cells sometimes called umbrella cells.

Sweat glands: Stratified cuboidal
Mesothelium: Simple squamous
Fallopian tube: Ciliated columnar

Simple cuboidal epithelium is present in: 
1. Lining epithelium of thyroid follicles
2. Smaller ducts of exocrine glands
3. Covering of the ovary (germinal epithelium)
4. Choroid plexus
5. Inner surface of lens of eyeball
6. Pigmented cell layer of retina
7. Duct of Bartholin gland
8. Some part of tubules in kidney (DCT) Covering, secretion

Deep to the capsule the lens is covered on its anterior surface by a lens epithelium. The cells of the epithelium are cuboidal. However, towards the periphery of the lens the cells become progressively longer. Ultimately, they are converted into long fibres that form the substance of the lens.

Ovarian cortex is covered by the germinal epithelium which is made up of a single layer of cuboidal cells in younger age. 

Features of epithelium:
- Epithelial tissues are composed of closely aggregated polyhedral cells adhering strongly to one another and to a thin layer of extracellular matrix (ECM).
- The forms and dimensions of epithelial cells range from high columnar to cuboidal to low squamous cells. Epithelial cell nuclei vary in shape corresponding roughly to the cell shape.
- Epithelium is an avascular structure. It receives nutrition by diffusion.
- The epithelia have got nerve supply
- Epithelial cells rest on basement membrane. 
- Epithelial cells show various types of junctions with adjacent cells and basement membrane.
- Epithelial cells isolate deeper structures from surface environment.
- Epithelial cells show surface modifications as per functional need. 
- Epithelial cells undergo mitosis and can regenerate damaged portion.
- Epithelium is derived from all three germ layers.
- Epithelial cells generally show polarity.
