The cuticle is the outer scale section of the hair. it contains 10% of the hair"s weight. A healthy cuticle will result in a shine, glossy. smooth and soft textured hair.
The cortex is the inner section of the hair shaft. This contains for 75% of the hair's strength. In the cortex is where the chemical bonds are broken.
The medulla this is in the innermost part of the hair. It consist of tunnels of cells filled with air spaces running continuously or intermittently through the hair. A medulla is present in most hair type except thin.

What are the three main layers of the hair shaft?
The three main layers of the hair shaft are the medulla (innermost layer), cortex (middle layer), and cuticle (outer layer). The medulla is the innermost part of the hair shaft, often absent in fine hairs. The cortex provides strength, color, and texture to the hair, while the cuticle is the protective outer layer made up of overlapping scales.
What are 3 layers of hair?
The three layers of hair are the cuticle (outermost layer), cortex (middle layer responsible for strength and elasticity), and medulla (innermost layer, not always present in all hair types). These layers work together to provide structure and protection to the hair strand.
What are the different parts of a strand of hair and how do they contribute to its overall structure and function?
A strand of hair consists of three main parts: the cuticle, cortex, and medulla. The cuticle is the outermost layer that protects the hair shaft. The cortex is the middle layer that provides strength and elasticity to the hair. The medulla, if present, is the innermost layer that adds structure and support. These parts work together to give hair its strength, flexibility, and texture.
What gland has a cortex and medulla?
The adrenal gland has a cortex and medulla. The adrenal cortex produces steroid hormones such as cortisol, while the adrenal medulla produces hormones like adrenaline and noradrenaline.
What is the cellular composition of hair?
Hair is primarily made up of a protein called keratin, which is produced by hair follicles in the skin. The hair shaft consists of three layers: the cuticle, cortex, and medulla. The cuticle is the outermost layer that protects the hair, the cortex provides strength and color, and the medulla is the innermost layer that helps with flexibility. Additionally, hair follicles contain cells that produce pigment, oil, and other substances that contribute to the overall composition of hair.
What are the names of the parts of the hair?
The cuticle, the cortex and the medulla.
What are the layer of the hair?
cuticle, cortex, and medulla (outer to inner)
What is the Substance made of keratin and is composed of the cuticle cortex and medulla?
Hair
What is in a hair?
there is 3 sections to hair 1. cuticle (outer part) 2. cortex 3. medulla (center)
What are the three main parts of hair?
Three major parts of hair are Cuticle, Cortex, and Medulla.

What are the three main parts of wool?
The three main parts of wool are the cuticle, cortex, and medulla. The cuticle is the outer layer that consists of overlapping scales, providing protection and influencing the wool's texture. The cortex makes up the bulk of the wool fiber, containing long chains of keratin that contribute to its strength and elasticity. The medulla is the innermost layer, which can be hollow or filled with air, affecting the wool's insulation properties.

What are names of the three layers of every hair strand?
The three layers of every hair strand are the cuticle, cortex, and medulla. The cuticle is the outermost layer, consisting of overlapping scale-like cells that protect the hair. The cortex is the middle layer, providing strength, color, and texture, while the medulla is the innermost layer, which may be absent in some hair types and is thought to have a role in the hair's overall structure.
What separate the renal cortex from the medulla?
The renal medulla is composed mostly of collecting ducts and the nephron loops. You will not see any glomeruli in the medulla, as they are confined to the cortex. This makes the renal cortex and renal medulla easily distinguishable.
What are the three main regions of the kidney in their correct sequence from outermost to innermost?
renal cortex > renal medulla > renal pelvis1.renal medulla>renal pelvis>renal cortex2.renal medulla>renal cortex>renal pelvis3.renal cortex>renal medulla>renal pelvis4.renal cortex>renal pelvis>renal medulla
