How many nerve cells are in a cubic centimeter of the human brain?
There are about 100 million nerve cells (neurons) in a cubic centimeter of the human brain.
The epidermis contains what?
The epidermis contains several layers of cells, including keratinocytes, melanocytes, Langerhans cells, and Merkel cells. It also contains nerve endings, blood vessels, and hair follicles.
Cells that have a definite nucleus that contains DNA?
These cells are eukaryotic cells. They have a defined nucleus enclosed by a nuclear membrane that contains the DNA. Examples include animal, plant, fungi, and protist cells.
The basal cell layer contains special cells called?
The basal cell layer contains special cells called:
Do B cells have antibodies on their surface?
Yes, B cells have antibodies on their surface that help them recognize and bind to specific antigens.
How many cells are in 1 square centimeter of your skin surface?
1 square centimeter of your skin's surface contains over 100,000 cells.
How many cells are in a square centimeter?
Roughly 1 billion but who's counting? There are 10 to 100 million viruses in one cubic cm of water or one gram of soil, unless I miss my guesstamate.
Do skin cells have ribosomes?
Skin cells on the surface are dead and therefore do not contain any functional organelles. The hypodermal layer (the layer beneath the visible skin) has active cells and contains ribosomes.
How does insulin enter animal cells?
Cholesterol enters animal cells when the animal consumes and processes something that contains cholesterol. The cholesterol then enters through the cells permeable surface.
How many nerve cells are in a cubic centimeter of the human brain?
There are about 100 million nerve cells (neurons) in a cubic centimeter of the human brain.
In one hour how many skin cells does your body loose and replace?
The human skin cell shedding rate (called the desquamation rate) depends on factors such as the location of the skin being considered, the total area being considered, and the person's age. Even keeping the skin location, skin area, and age constant will result in different rates for different individuals. As an example, if we take the average rate of all subjects and all sample areas given in the Table 2 referenced above, we obtain an average rate of 945 cells per square centimeter per hour. Let's assume 945 cells per square centimeter per hour is close to the average desquamation rate for the entire body even though it depends on location and the table gives actual rates that vary from a low of 530 to a high of 1856. There are 10,000 square centimeters in a square meter. Average adult humans have a skin area of somewhere between 1.5 and 2.0 square meters. This means the average adult human has somewhere between 15,000 and 20,000 square centimeters of skin. Multiplying this area by the average of 945 cells per square centimeter per hour gives us 14,175,000 to 18,900,000 cells per hour or 340,200,000 to 453,600,000 cells per day
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.
In cells structure that contains the cells genetic material and controls the cells activities?
Which structure contains a eukaryotic cells genetic material
The epidermis contains what?
The epidermis contains several layers of cells, including keratinocytes, melanocytes, Langerhans cells, and Merkel cells. It also contains nerve endings, blood vessels, and hair follicles.
Which layer of cells contains vascaular tissue?
Which layer of cells contains vascular tissue
Have dead cells why is it an advantage to on the surface of the body?
Why is it an advantage to have dead cells on the surface of the body? Why is it an advantage to have dead cells on the surface of the body?
What are surface cells?
Surface cells refer to the outermost layer of cells on an organism's surface. These cells serve various functions, such as protection, sensation, absorption, and secretion. In humans, surface cells can be found in the skin, lining of the gut, and respiratory tract.
