Body Membranes
This membrane lines body tracts that open to the outside, such as the digestive and respiratory tracts.
Mucous Membrane
This outer layer of the skin is made of epithelial cells
Epidermis
Identify the Epithelium tissue shown in this shown.
Simple Squamous Epithelium
What is the primary function of epithelial tissue?
Protection
What are the three layers of the hair shaft, from innermost to outermost?
Medulla —> Cortex —> Cuticle
This membrane is also known as the skin and covers the external surface of the body
Cutaneous Membrane
This skin layer is composed of dense irregular connective tissue
Dermis
Identify the epithelial tissue shown in this image.
Stratified Cuboidal Epithealium
Which type of tissue contracts to produce movement?
Muscle Tissue
What is the difference between the hair shaft and the hair root?
The hair shaft is the portion of the hair that projects above the skin, while the hair root is the portion enclosed within the hair follicle
Unlike mucous membranes, which line passages open to the exterior, these membranes line closed internal body cavities
Serous Membrane
This layer contains loose areolar connective tissue and adipose tissue and connects the skin to underlying bones.
Hypodermis
This connective tissue contains chondrocytes located in spaces called lacunae. Identify the tissue shown.
Hyaline Cartilage
A tissue contains cells that are tightly packed together with very little extracellular space and is commonly found lining organs and body cavities. What type of tissue is it?
What structure in the hair bulb contains rapidly diving cells that produce the hair?
Hair Matrix
This membrane lines joint cavities and produces a fluid that reduces friction between moving surfaces
What is a synovial membrane
The epidermis is described this way because it does not contain blood vessels
Avascular
Which major tissue type contains an extracellular matrix that can range from liquid, as in blood, to hard, as in bone?
Connective Tissue
What structure supplies the hair matrix with nutrients needed for hair growth, and what does it contain?
The lining of the abdominal cavity belongs to a membrane type that is specifically associated with closed body cavities. Name the membrane and the abdominal cavity it lines.
Serous membrane; peritoneal cavity
Name the five epidermal layers from superficial to deep
Stratum Corneum, Stratum Lucidum, Stratum Granulosum, Stranum Spinosum, and Stratum Basale
This connective tissue is composed of densely packed, parallel collagen fibers that provide strong resistance to tension in one direction. Identify the tissue shown.
Epithelial, Connective, Muscle, and Nervous Tissue
What muscle is attached to the hair follicle, and what happens when it contracts?
The arrector pili is a smooth muscle attached to the hair follicle. When it contracts, it pulls the hair upright and produces goose bumps.
Arrector contracts -> hair raises -> goose bumps
