1
Question
Integumentary System
Answer
The organ system that consists of the skin, hair, nails, and glands, and provides protection, regulation, and sensation.
2
Question
Histology
Answer
The study of tissues and how they are arranged into organs.
3
Question
Tissue
Answer
A group of similar cells and cell products that arise from the same region of an embryo and work together to perform a specific structural or physiological role in an organ.
4
Question
Epithelial Tissue
Answer
Tissue that consists of a flat sheet of closely spaced cells, one or more cells thick, and covers the body surface, lines body cavities, forms the external and internal linings of many organs, and makes up most gland tissue.
5
Question
Connective Tissue
Answer
The most abundant, widely distributed, and variable tissue that provides support, protection, and movement for the body.
6
Question
Nervous Tissue
Answer
Tissue that consists of neurons (nerve cells) and glial cells (supporting cells) and is responsible for detecting stimuli, transmitting signals, and coordinating the body's responses.
7
Question
Muscular Tissue
Answer
Tissue that consists of elongated cells that are specialized to contract and exert force on other tissues and organs.
8
Question
Gland
Answer
A cell or organ that releases substances for use elsewhere in the body or for elimination from the body.
9
Question
Exocrine Glands
Answer
Glands that release their secretions onto a surface by way of ducts.
10
Question
Endocrine Glands
Answer
Glands that release their secretions into the bloodstream and are not equipped with ducts.
11
Question
Muscular Tissue
Answer
Consists of elongated cells that are specialized to contract and exert force on other tissues and organs. There are 3 types of muscle: skeletal, cardiac, and smooth.
12
Question
Skeletal Muscle
Answer
Striated and voluntary muscle. Made up of muscle fibers.
13
Question
Cardiac Muscle
Answer
Striated and involuntary muscle. Made up of myocytes.
14
Question
Smooth Muscle
Answer
Non-striated and involuntary muscle. Found in the walls of hollow organs. Made up of myocytes.
15
Question
Gland
Answer
A cell or organ that releases substances for use elsewhere in the body or for elimination from the body.
16
Question
Secretion
Answer
A product released by a gland that is useful to the body.
17
Question
Excretion
Answer
A waste product released by a gland.
18
Question
Exocrine Glands
Answer
Glands that release their secretions onto a surface or into the cavity of another organ through a duct.
19
Question
Endocrine Glands
Answer
Glands that release their secretions directly into the bloodstream.
20
Question
Modes of Secretion
Answer
Different ways in which glands release their secretions. Examples include serous, mucous, mixed, eccrine, apocrine, and holocrine.
21
Question
Serous Glands
Answer
Produce thin, watery fluid. Examples include perspiration, tears, and digestive juices.
22
Question
Mucous Glands
Answer
Secrete a glycoprotein called mucin, which absorbs water and forms sticky mucus.
23
Question
Mixed Glands
Answer
Contain both mucous cells and serous cells.
24
Question
Eccrine Glands
Answer
Release their products by exocytosis. Packaged in the Golgi Apparatus.
25
Question
Apocrine Glands
Answer
Produce their products in the cytosol, which are then released by budding from the apical cell surface with a thin coating of cytoplasm and plasma membrane.
26
Question
Holocrine Glands
Answer
Gland cells break down entirely and become the secretion.
27
Question
Mucous Membranes (Mucosa)
Answer
Consist of an epithelium overlaying a layer of areolar tissue and often a thin layer of smooth muscle. Have absorptive, secretory, and protective functions. Often covered with mucus.
28
Question
Serous Membrane (Serosa)
Answer
Line the thoracic and abdominal cavities and cover the external surfaces of organs. Composed of simple squamous epithelium resting on a thin layer of areolar connective tissue. Produce watery serous fluid.
29
Question
Parietal
Answer
Line the outside of a cavity.
30
Question
Visceral
Answer
Line the outside of an internal organ or structure.
