Why is histology important in biology?
It helps understand tissue structure and function for medical diagnosis.
Integumentary system are composed of skin, hair, nails and glands. TRUE OR FALSE?
TRUE
What is the primary function of the hair bulb?
To nourish and ensure hair germination and proliferation.
The branch of biology that deals with the study of the structure and composition of tissues are termed histology.
HISTOLOGY
It is a chemical process that preserves biological tissues from decay and damage.
FIXATION
This process is commonly carried out by immersing specimens in a series of ethanol (alcohol) solutions of increasing concentration until pure, water-free alcohol is reached.
DEHYDRATION
It is a process in histology (the study of tissues under a microscope) that allows scientists to see tiny pieces of tissue (such as those from plants, animals, or humans) more clearly.
CLEARING
Histological technique wherein it involves with the immersion of tissue in molten paraffin or resin to fill structural spaces and provide mechanical support.
INFILTRATION
It refers to the process of enclosing tissue specimens in a solid medium to support sectioning thin slices that can be analyzed under a microscope. It ensures that the tissue retains its structure and integrity during slicing.
EMBEDDING
It is the last step in the series of histological preparation of a slide. This protects the cell film from damage, air drying and stain fading.
MOUNTING
What determines the frequency of hair regeneration?
The dermal papilla
Gland produces an oily substance called sebum
SEBACEOUS GLAND
What is the primary tissue type in sebaceous glands?
EPITHELIAL TISSUE
What is the primary function of the erector spinae muscle?
To extend and laterally flex the spine
What is the visible, non-living part of the hair that extends above the skin's surface?
HAIR SHAFT
What protein primarily composes the hair shaft?
KERATIN
