Explanation / Answer
Answer (14-16)
May indicate anger or sunburn- erythema
Usually indicates a disorder of liver – jaundice
Bluish color in light skinned individuals- cyanosis
Explanation: Jaundice is characterized as a condition in which the body attains a yellowish or a greenish pigmentation. It results due to the hyper secretion of bilirubin from the liver.
Cyanosis is characterized as a condition in which the skin gets discolored and attains a bluish or purplish pigmentation due to the insufficient amount of oxygen supply in the tissues
Erythema is characterized as the reddening of the skin as a result of the tissue injury. During anger and sunburn our skin turns red, hence is marked so.
Answer (17-20)
The most abundant cells of epidermis- keratinocyte
Proteins found in the epidermis responsible for the toughening of skin- keratin
Cells that functions as a sensory receptor for touch- Merkel cells
Skin macrophages that help activate and assist the immune system- Langerhans cells
Explanation:
Keratinocytes are the group of cells which are responsible for the synthesis of keratin. They constitute approximately 90 % of the outer epidermal layer.
Keratin is the protein found on the upper epidermal layer of the humans. This layer undergoes extreme wear and tear and is responsible for bearing and tolerating the stress induced in the skin.
Merkel cells are the cells which are oval in shape and are responsible for the light and touch sensations in the vertebrates. They are located in the skin surface of the vertebrates.
Langerhans cells are the macrophages which plays a very important role in inducing the immune responses. They perform phagocytosis and eats up the foreign antigens entering our body thus protecting us against the diseases.
Answer (21-25)
The lining of the bone marrow cavity- endosteum
Cells that can dissolve the bony matrix- osteoclasts
Layers of bone matrix- lamellae
Small channels that radiate through the matrix of bone- canaliculi
Cells that can build bony matrix- osteoblasts
Explanation:
Microscopic structures of a mammalian bone includes the regions like- (Outer –inner)
Periosteum
Matrix
Endosteum,
Bone marrow
Thus endosteum is the area which immediately surrounds the bone marrow cavity
The cells that form the bony matrix are called as osteocytes.
Osteo signifies bone and cyte represents the cells
Likewise the cells which helps in the resorption of the bony material is called as osteoclasts.
Osteo signifies bone and clasts means dissolving
The second layer of the bone; that is the matrix occurs in different layers. Those layers are called matrix.
An osteocyte in the matrix is surrounded by a layer of fine radiating channels which are called canaliculi. With the help of a canaliculi an osteocyte is in touch with another osteocyte.
