What is human Biology

Answer 1

The study of anatomy physiology development of the human body and biotic and a biotic factors that influence the well-being of the body

Question 2

Short note on Gross Anatomy

Answer 2

Examination of relatively large structures of features that are visible under an unaided eye it is divided into
regional anatomy
systematic anatomy
clinical anatomy surface anatomy

Question 3

Short notes on developmental anatomy

Answer 3

Changes in form that occur from fertilisation to physical maturity and death
Divided into embryology

Question 4

Short notes on microscopic anatomy

Answer 4

The study of features that cannot be seen without a magnet or a light microscope 
Divided into histology and cytology

Question 5

Regional anatomy

Answer 5

Each region of the body is studied separately and all aspects of that region are I studied at the same time

Question 6

Systemic anatomy

Answer 6

Each system of the body is studied and followed through out the entire body

examples of this would be your cardiovascular system nervous system digestive system

Question 7

Clinical anatomy

Answer 7

Application of anatomical knowledge to clinical problem-solving and clinical practice

Example radiographic anatomy

Question 8

Surface anatomy

Answer 8

Surface marking End of their relation to deeper surfaces

Question 9

Embryology

Answer 9

Study of development during the first eight weeks after fertilisation

Question 10

cytology

Answer 10

Study of internal structures of individual cells the simplest building blocks of life

Question 11

histology

Answer 11

Study of Tissues

Question 12

Four types of tissues

Answer 12

Epithelial tissue which covers the body surfaces line cavities and forms glands

Connective tissue: It’s good to support and binds organs stores energy reserves

Muscular tissue: Active generation of force to produce movement

Nervous tissue: Initiate transmits and interprets nerve impulses the coordinates body activity
