Overall function of the nervous system
Coordinate the body's systems by receiving and sending information
Type of cellular transport that uses energy
Active Transport

Connective
Parts of the bone. Name all 5
epiphysis, diaphysis, articular cartilage, periosteum, medulla
Synapse
Also known as supporting cells
Neuroglial cells
Diffusion and Osmosis are examples of:
Passive Transport
A type of dense connective tissue.
Cartilage
Mature bone cells enclose in tiny chambers called lacunae
Osteocytes
A disorder causing muscle weakness and leads to reduce mobility

What happens to the cell in telophase? List all 5
Chromosomes disappear, nuclear membrane reforms, nucleoli reappears, spindle disappears, centrioles duplicate
Which epithelium participates in functions like the diffusion of nutrients from the blood to the body tissues and the diffusion of gases in the alveoli of the lungs?
