Physiology of Ageing Revision 1

Which of the following are the cells which produce collagen and are the only living cells in the dermis?

• Collagen

• Elastin

• Fibroblasts

• Collagenases

These are enzymes that, when activated, control tissue degradation in the dermis.

• Matrix Metalloproteinase

• Advanced Glycation End Products

• Extra Cellular Matrix

• Pro Collagen

Which organelle within the cell are densely packed and provide a constant flow of Adenosine Triohosphate (ATP)

• Ribosomes

• Nucleus

• Golgi Body

• Mitochondria

What is a band of dense, connective tissue that connects one bone to another bone?

• Muscle

• Fascia

• Tendon

• Ligament

The stem cells of bone and the source of new fibroblasts are called.........

• Osteoblasts

• Osteoclasts

• Osteoprogenitor

• Osteocytes

This classification of bone, is also known as cortical bone, and makes up approximately 80% of the bone in the human skeleton?

• Cancellous

• Compact

• Osteoid

• Sesamoid

The conditions inside our body must be very carefully controlled if the body is to function effectively. This process of maintaining a constant internal environment is known as:

• Homeostasis

• Haemophilia

• Hirsutism

• Hyperpigmentation

There are four types of tissues in the body. They are classified as:

• Epithelial, Constructive, Muscle and Nervous

• Epithelial, Connective, Muscle and Nervous

• Epithelial, Connective, Muscle and Corneum

• Epithelial, Connective, Melanin and Nervous

What is the only liquid connective tissue?

• Saliva

• Lymph

• Sebum

• Blood

Their primary function is to protect the body against foreign microbes in immune responses.

• Leucocytes

• Erythrocytes

• Thrombocytes

• Osteocytes
