Study Notes
Lymphoid System
- Undifferentiated cells around the wall of capillaries are called Pericytes.
- Thymus dependent zones are present in the Paracortex of the lymph node.
Thymus
- The thymus is an organ that has both lymphoid and endocrine functions.
Tonsils

- The Palatine tonsil is located in the Oropharynx.
Skin
- Langerhans cells are a type of macrophage found in the skin.
- Merkel cells are mechanoreceptors.
- Apocrine sweat glands are found in the axilla.
Respiratory System
- The layer under the epithelium of the trachea is Connective tissue.
- Type II pneumocytes secrete Surfactant.
- Type I pneumocytes are Simple cuboidal epithelium.
Blood Air Barrier
- The blood air barrier does not include the Cytoplasm and basement membrane of the Type II pneumocyte.
Tongue
- Filiform papillae do not contain taste buds.
- The epithelium layer of the dorsal surface of the tongue is Stratified squamous epithelium.
- Taste buds contain Neuro-epithelium.
Esophagus
