Question

Macrophages and leucocytes exhibit-

• A. Ciliary movement
• B. Flagellar movement
• C. Amoeboid movement
• D. Gliding movement

Answer 1

The correct option is C Amoeboid movement

Some specialized cells in our body like macrophages and leucocytes in blood exhibit amoeboid type of movement. It is effected by Pseudopodia formed by the streaming of protoplasm(as in Amoeba) cytoskeletal elements like microfilaments which are also involved in Amoeboid movement.

The rhythmic, sweeping movement of epithelial cell cilia, of ciliate protozoans, or the sculling movement of flagella, possibly resulting from the alternate contraction and relaxation of contractile threads (myoids) on one side of the cilium or flagellum.

Movement of one surface over another without angular or rotatory movement is known as gliding movement. This type of movement occurs in the carpal joints of the wrist, the tarsal joints of the ankle show gliding movement.

So, the correct answer is option 'c'.
