Front

What do osteoblasts do?

Back

Osteoblasts secrete osteoid, which is the organic component of the bone matrix.

Front

What is the function of the root hair plexus?

Back

The root hair plexus allows the hair to assist in touch sensation.

Front

What bones form part of the nasal septum?

Back

The vomer and ethmoid bones form part of the nasal septum.

Front

Which cells are responsible for bone resorption?

Back

Osteoclasts are the cells that accomplish bone resorption.

Front

What is the role of osteocytes in bone tissue?

Back

Osteocytes maintain the bone matrix and communicate with other bone cells.

Front

What is the primary function of osteoclasts?

Back

Osteoclasts break down bone tissue during the process of bone remodeling.

Front

What is the significance of sutures in the skull?

Back

Sutures are fibrous joints that unite the bones of the skull, providing stability and protection.

Front

What is the difference between osteoblasts and osteoclasts?

Back

Osteoblasts build bone by secreting osteoid, while osteoclasts break down bone.

Front

What is the structure that binds the hair root to the dermis?

Back

The hair follicle binds the hair root to the dermis.
