what is pH? | pH is measures the concentration of acidity and alkalinity of hydrogen ions in fluids. its on a scale that runs from 0-14. 0-6 acidic 8-14 basic, alkaline. |
what is the cellular structure made up of? | nucleus, plasma membrane, mitochondria, golgi apparatus, ribosomes, lysosomes and peroxisomes. |
stratum basale | This layer is made up of a one row of column shaped keratinocytes which are called basal cells. Keep in mind that this is the very bottom layer. The cells in the stratum basale divide and renew to aid in maintaining or repairing the skin. |
stratum spinosum | The spinosum in above the stratum basale layer which is responsible for creating keratin that gives proteins to our skin, nails, and hair. This layer is about five to ten cells thick and is also known as the squamous cell layer. |
stratum granulosum | The stratum granulosum lies above the stratum spinosum which is a rigid cell layer. They are flat and without nuclei. The membranes are thicker and in this layer is where keratin and keratohyalin is produced in large amounts. |
stratum lucidum | The lucidum only are found on the palms and soles. Its job is to reduce friction between the corneum and granulosum. The name itself comes from the latin for "clear layer." which describes the transparency of the cells themselves.(Heather, 2024) |
stratum corneum | The corneum layer is the last layer thats considered dead. They are flat / contain keratin proteins. This layer provides strength and absorbs water. acts as a barrier to any chemicals that might harm the living cells just beneath them. (Heather, 2024) |
different types of tissues | myeloid - hyaline - elastic - fibrocartilage |
what are the abdominal wall muscles? | rectus abdominis external oblique internal oblique transversus abdominis |
which of the four muscles is teh strongest flexor of the vertebral column? | rectus abdominis |
why are the direction of fibers important? | they aid in making the abdominal wall strong |
