What makes up most of the middle layer in the heart wall?
Most of the middle layer in the heart wall is composed of cardiac muscle cells. Cardiac muscle cells are also known as cardiomyocytes.
What part of the hair shaft is made of cortical cells?
The cortex layer of the hair shaft is made of cortical cells. It is the middle layer of the hair shaft and provides strength, elasticity, and color to the hair.
What is the biology term for the middle layer of the leaf?

The middle layer of cells is the?
Skin cells layer in a very straightforward way.First, is the Epidermis, A larger description of the strateum corneum (what you see) with the new skin layer is right beneath.Then the Dermis contains the sweat gland, the erector muscle, and the sebaceous gland.Last there is the Subcutaneous layer containing fat cells and the hair folicle.
Why are mesophyll cells are named so?
Mesophyll cells are named as such because they are located in the mesophyll layer of plant leaves. This layer is where photosynthesis primarily occurs, as it contains a high concentration of chloroplasts in the mesophyll cells to help with the process of converting sunlight into energy.
How many layers of cells does roundworm have?
The body has three tissue layers and a fluid-filled false body cavity, meaning the cavity is between the inner and middle layers rather than the middle layer and the outer layer, as it is in complex animals.
What encloses the cortex of a root?
The endodermis and pericycle serve to enclose the cortex of a root. The endodermis is a single layer of cells that regulates the movement of water and nutrients into the vascular cylinder. The pericycle is a layer of cells that gives rise to lateral roots in plants.
What layer of skin that contains the blood vessels and nerves closest to the surface of of the skin is?
The upper layer of the skin is called the 'epidermis'. In birds, it contains no nerve cells, and their Merkel cells are located in the dermis. However, in most animals it contains a scattering of nerve cells called Merkel cells, located at the basal layer. The middle layer of the skin is called the 'dermis.' It contins blood vessels, most of the nerve cells, and other structures. The lower layer of the skin is called the 'sub-cutis' and mostly contains fat.
What is middle layer of the troposphere?
The middle layer of the atmosphere is the Mesosphere.
Which layer of the skin produces the skin cells?
The Bascal Cell Layer, the deepest layer where cells divide to produce new skin cells.
What is the middle layer of your skin?
sebaceous The dermis is the middle layer of skin. The outer layer is the epidermis, and the inner layer is the hypodermis. NO... The answer is DERMIS... NOT Brock layer...
What are the layer of vascular wall?
The layers of the vascular wall are the tunica intima (innermost layer), tunica media (middle layer), and tunica adventitia (outermost layer). The tunica intima is composed of endothelial cells and connective tissue, the tunica media contains smooth muscle cells, and the tunica adventitia consists of connective tissue and supportive structures.
