2.leukocytes (WBC's)
3.thrombocytes (platelets) - Flat sheets of pliable tissue that covers or lines a part of the body?
- Membranes
- A mucous membrane (mucosa) lines a body cavity that DOES NOT open directly to the exterior? T/F
- False- It DOES open directly to exterior
- A serous membrane (serosa) lines a body cavity that DOES NOT open directly to the exterior? T/F
- True
-
Serous membrane lining the lungs is called?

B. pleura
C.lamina - B. pleura
- What two layers make up the serous membrane?
-
1. parietal layer-layer attached to cavity wall.
2. visceral layer-layer that covers & attaches to organs inside the cavity. - The serous membrane lining the abdominal cavity & covering the abdominal organs is the peritoneum? T/F
- True
- The cutaneous membrane (skin) covers the surface of the body & consists of a superficial portion called the epidermis & a deeper portion called the dermis?
- True
- Lines the cavities of freely movable joints, and DOES NOT open to the exterior?
- synovial fluid
- Is secreted in the synovial membrane & lubricates & nourishes the cartilage covering the bones at movable joints?
- Synovial fluid; contains macrophages that remove microbes & debris from the joint cavity.
- The combination of an epithelial layer & an underlying connective tissue layer constitutes an?
- epithelial membrane
- Consists of elongated cells called muscle fibers that can use ATP to generate force?
- muscle tissue

A.maintains posture
B.provides protection
c.produces movement
D.maintains homeostasis - D. maintains homeostasis
- Attached to bones & is striated & voluntary?
- skeletal muscle
- Forms most of the wall of the heart; is striated, but is involuntary?
- cardiac muscle
- Where would you find intercalated discs?
- cardiac muscle tissue
- What is the purpose of gap junctions in cardiac muscle tissue?
- provides a route for quick conduction of muscle action potentials throughout the heart.
- Is found in the walls of hollow internal structures (blood vessels), is nonstriated & involuntary?
- smooth muscle tissue- (ex.gallbladder, urinary bladder)
- Composed of neurons and neuroglia?
- Nervous tissue
- Neurons are sensitive to various stimuli? T/F
- True
- Neuroglia do not generate or conduct nerve impules, but have many supportive functions? T/F
- True
- During tissue repair new cells originate by cell division from the _______ , or the __________?
-
1. Stroma-the supporting connective tissue "honeycomb"
2. parenchyma- cells that constitue the functoing part of the tissue or organ. "honey" - formation of scar tissue
