Question

The study of tissue is known as
A) Histology
B) Cytology
C) Dermatology
D) Cardiology

Answer 1

Hint: ‘Logy’ is a suffix that is used with most of the terms denoting the study of those terms. ‘Logy’ means the study of. The prefix used before the suffix ‘logy’ denotes the subject that we are studying.

Complete answer:
Biology is the science which includes the study of living organisms and all kinds of life present in our universe. To study biology properly, anatomy and morphology or organisms have to be studied deeply. To find similarities, differences, to study their mode of living, their nutrition, the working of their organs based on their different habitats and many more things that an organisms constitutes, to study all this the organism's anatomy and morphology has to be studied by deeply studying the way its cells are arranged, how their tissues are made, how their organs are working and this can be done by different branches of biology which deal with the microscopic study of cells, tissues and organs.
Cytology – The branch of science which deals with the detailed study of cells and their organelles.
Histology – The branch of science which deals with the detailed study of tissues and cells that make them along with the arrangement and structure of cells.
Dermatology – It is the detailed, in depth study of our skin and how it changes with the internal and external factors.
Cardiology – Includes the detailed study of the heart.
There are many other branches of study that come under biology like Craniology (Study of skulls), Embryology (Study of embryo), Haematology (Study of blood) and many more.

So, the answer for this question is option A– The study of tissue is known as Histology.

Additional Information: Histology is also known as Microscopic anatomy/ Microanatomy.
Histopathology – In this branch of histology diseased tissues are being studied.
Samples that are to be studied histologically have to be prepared properly before being observed. They are trimmed and embedded in wax slabs and then cut into very thin almost transparent slices which are fixed with the help of chemicals so that they can be preserved for longer durations and can be used for observation whenever required.

Note: The tissue to be observed needs a hard surface for support but paraffin wax is not a reliable option for longer preservation of histological slides as the wax can melt with little increase in temperature so other alternatives to be used can be – acrylic, gelatin, and epoxy.
