Chapter 2 Introduction to Veterinary Science (2nd Edition)

Tissue

Collection of cells organized for a particular function.

Organs

Collections of tissue.

Displaced Abomasum

Condition commonly called a twisted stomach in which the fourth stomach of a cow fills with gas and I pulled upward; commonly occurs shortly after calving.

Foot-and-Mouth Disease

Highly infectious viral disease that selectively attacks epithelial tissue in cloven-hoofed animals.

Epithelial Tissues

Collection of cells that line the body's surface and openings.

Basement Membrane

Collection of fibers that ties the epithelial layer to the underlying connective tissue.

Integument

Skin.

Keratin

Specialized protein deposited in cells giving a typical hardness and durability.

Tendons

Connective tissue that attaches muscles to bones.

Ligaments

Connective tissue that attaches bones to bones.

Adipose Tissue

Fat.

Myofiber

Muscle cell.

Porcine Stress Syndrome

Swine condition in which calcium leaks from the endoplasmic reticulum, causing pigs to shake involuntarily.

Rigor Mortis

Muscle stiffness occurring after death.

Hypocalcemia

Condition commonly referred to as milk fever; cause by low blood calcium occurring at parturition.

Sweeny

Nerve damage and resultant shoulder muscle shrinkage occurring in draft horses from pulling harnesses.

Central Nervous System

Brain and spinal cord.

Neuron

Nerve cell.

Trying up or Monday-Morning Disease

Cramping with potential muscle damage in working horses that occurs the Monday after a weekend of rest and full feed.

Horner's Syndrome

Nerve damage that causes several eye malfunctions, including pupil constriction, eyelid drooping, protrusion of the third eyelid, and sunken eyes.

True or False: Hair is epidermal tissue.

True.

True of False: Kidney damage may occur in Monday-Morning disease.

True.

Which of the four stomachs of a cow becomes displaced when a twisted stomach occurs?

Abomasum.

What type of tissue lines the body's surface and openings?

Epithelial.

What type of epithelial tissue lines the urinary tract?

Transitional epithelium.

What type of tissue is under attach in foot-and-mouth disease?

Epithelial tissue.

Name the hairlike extension from the nerve cell body that carries the nerve impulse.

Axon.

After death, the body lacks energy to pump calcium back into the endoplasmic reticulum. Consequently, the body stiffens. Name this condition.

Rigor Mortis.

Why do light-colored horses have a higher incidence of melanoma than dark-colored horses?

Because they have less pigment.

Describe the shape of squamous cells.

Flat.

Differentiate between tendons and ligaments.

Ligaments connect bone to bone and tendons connect bone to muscle.

List the three muscle types.

Cardiac, smooth, and skeletal.

List two involuntary muscle types.

Cardiac and smooth.

List three types of neurons.

Sensory, motor, and interneurons.
