Cellular Classification: Identify the class to which each of the following cells belong. _________ adipocyte _________ myofiber _________ B cell __________ neuron ___________ ciliated columnar cell __________ osteocyte ___________ erythrocyte __________ rods & cones ____________ goblet cell ___________ Schwann cell ___________ macrophage __________ thrombocyte CONNECTIVE EPITHELIAL MUSCLE NERVOUS

Solution

Ans. A. Connective Tissue-

I. Blood- B cell, Erythrocyte (= RBC), Macrophages, Thrombocyte

II. Bone – Osteocyte

Adipocytes

Note: Blood is a connective tissue. B cell (B-lymphocyte), erythrocytes, macrophages, and thrombocytes are component of blood. Macrophages may also be fixed in other connective tissue where they engulf dead cells and invading antigens. Osteocyte is a cellular component of bond (a connective tissue). Adipocyte is also a cellular component of connective tissue that serves to store fats.

B. Epithelial Tissue – Ciliated columnar cell, goblet cell.

Note: Columnar epithelial cells line the lumen of digestive tract. Goblet cell is a glandular epithelial cell that secretes mucus.

C. Muscle Tissue – Myofiber,

Myofiber is multinucleated myocyte.

D. Nervous Tissue- Rods & cones, neuron, Schwann cell.

Rods & cones are photosensitive specialized neurons. Schwann cell is a component of peripheral nervous system that produces myelin sheath around axon of neurons.
