48
Q

This occurs when water concentration is unequal between the extracellular and intracellular space. The membrane must be permeable to water molecules and impermeable to dilute molecules because it is the solutes that cannot freely pass through the membrane that are osmotically active.

49
Q

Outside

Inside

51
Q

K+ has a high concentration ____ the cell and a low concentration _____.

A

Inside

Outside

52
Q

How does the sodium potassium ATPase work?

A

A channel is open to the intracellular space where 3 sodium ions attache itself. An ATP then gives its energy to close the channel which opens to the extracellular space. The sodium exits and 2 potassium ions enter and then open to the extracellular space.

53
Q

Describe the pathway through the organelles that a protein will follow while it is being made. From ribosomes to plasma membrane.

A
  1. Ribosomes package the DNA
  2. ER transports the protein in the cell
  3. Golgi apparatus moves the protein from the ER to outside of the cell where a vesicles has broken off carrying the protein.
  4. Plasma membrane transports the protein on the surface and sends out messenger proteins to other cells.
54
Q

This is the most abundant cell in the epidermis. It is a tough fibrous protein that protects against acids, bases and scrapes. Desmosomes connects them to each other. Less deep, more superficial

55
Q

Where are sensory receptors located in the skin?

A

Merkel cells deep in the epidermis
Hair follicle receptors
Pacinian receptors deep in the dermis or subcutaneous layer

56
Q

What are the 2 main structures to a long bone?

A
  1. Diaphysis

2. Epiphysis

57
Q

This is the shaft of the long bone made up of thick bone around medullary cavity it contains yellow marrow (fat) in adults.

58
Q

This is the ends of a long bone. It is composed of compact bone surrounding spongy bone.

59
Q

This separates the diaphysis from the epiphysis.

A

Epiphyseal line

60
Q

This is the outer surface of a long bone. It is a fibrous layer that contains irregular connective tissue and an osteogenic layer that contains osteoblasts and osteo clasts.

A

Periosteum

61
Q

This is the inner portion of a long bone that contains connective tissue with osteoclasts and osteoblasts.

62
Q

Where are long bones found?

64
Q

How do flat bones develop?

A

Intramembranous Ossification
