Bone Structure
This central canal contains blood vessels and nerves in compact bone.
What is the Haversian Canal?
These star-shaped cells make fibers in connective tissue.
What are Fibroblasts?
This muscle tissue has striations, is voluntary, and nuclei are pushed to the edges.
Voluntary
Connective tissue is made of __________ fibers and __________ substance.
What are protein fibers and ground substance?
This type of cartilage is found at the ends of bones and in the nose and trachea.
What is hyaline cartilage?
The structural unit of compact bone is called this.
Osteon
These cartilage cells live in lacunae.
What are Chondrocytes?
This muscle tissue has striations, is involuntary, and contains intercalated discs.
Cardiac Muscle
Compared to epithelial tissue, connective tissue cells are more __________.
What is spread apart?
The extracellular matrix of blood is called this.
What is plasma?
Osteocytes are found within these small spaces.
What are Lacunae?
Immature version of a bone cell
Osteoblast
This muscle tissue has no striations and one central nucleus per cell.
Smooth Muscle
This is the most abundant connective tissue by mass.
What is connective tissue?
These membranes line cavities that open to the outside and contain goblet cells.
What are mucous membranes?
These rings of bone matrix surround the central canal.
What are Lamellae?
These immune cells release histamine and heparin.
What are Mast cells?
In epithelial tissues, nuclei are lined up at the base of the cells in this type.
What is simple columnar epithelium?
Most connective tissues are well vascularized, except these two.
What are cartilage and dense regular connective tissue?
These membranes line body cavities without openings to the outside and secrete a slippery fluid.
What are serous membranes?
These tiny channels connect osteocytes to each other and to blood supply.
What are Canaliculi?
These large cells come from monocytes and engulf foreign particles.
What are Macrophages?
Flat, thin epithelial cells form this tissue type that allows diffusion.
What is simple squamous epithelium?
Name the three connective tissue fibers and a role of each.
What are collagen (strength), elastic (stretch/recoil), reticular (support framework)?
These membranes are made of connective tissue only and are found in joints.
What are synovial membranes?
