Name the cells/tissues in the human body which:
$(a)$ exhibit amoeboid movement
$(b)$ exhibit ciliary movement

(N/A) Amoeboid movement: Macrophages and leucocytes (like neutrophils and monocytes) present in the blood exhibit amoeboid movement. This movement is achieved by the formation of pseudopodia.
$(b)$ Ciliary movement: Ciliated epithelial cells present on the surface of internal tubular organs,such as the trachea,vasa efferentia,and fallopian tubes,exhibit ciliary movement. This movement helps in the passage of substances like mucus or ova.
