|
What is adipose tissue?
|
Tissue composed of fat cells
|
|
|
What is Axon?
|
A long extention of a nerve cell, extending from the cell body to synaptic endings on other nerve cells or on muscles
|
|
|
What is blood?
|
A fluid of plasma in which blood cells are suspended: carried within the circulatory system.
|
|
|
What is bone?
|
A hard, mineralized connective tissue that is a major component of the vertebrate endoskeleton: provides support and sites for muscle attachment.
|
|
|
What is a cardiac muscle?
|
The specialized muscle of the heart,able to initiate its own contraction, independent of the nervous system.
|
|
|
What is cartilage?
|
A form of connective tissue that forms portions of the skeleton: consits of chondrocytes and their extracellular secretion of collagen: resembles flexible bone.
|
|
|
What is cell body?
|
The part of a nerve cell in which most of the common cellular organelles are located: typically a site of integration of inputs to the nerve cell.
|
|
|
What is collagen?
|
A fibrous protein in connective tissue such as bone and cartilage.
|
|
|
What is connective tissue?
|
A tissue type consisting of diverse tissues, including bone, fat, and blood, that generally contain large amounts of extracellular material.
|
|
|
What is dendrite?
|
A branched tendril that extends outword from the cell body of a neuron: specialized to respond to signals from the external enviornment or from other neurons.
|
|
|
What is dermis?
|
The layer of skin beneath the epidermis: composed of connective tissue and containing blood vessles, muscles, nerve endings, and glands.
|
|
|
What is the endocrine gland?
|
A ductless, hormone-producing gland consisting of cells that release their secretions into the extracellular fluid from which the secretions diffuse into nearby capillaries.
|
|
|
What is the epidermis?
|
In animals, specialized epithelial tissue that forms the outer layer of skin.
|
|
|
What is epithelial tissue?
|
A tissue type that forms membranes that cover the body surface and line body cavities, and that also gives rise to glands.
|
|
|
What is the exocrine gland?
|
A gland that releases its secretion into ducts that lead to the outside of the body or into the digestive tract.
|
|
|
What is a gland?
|
A cluster of cells that are specialized such as sweat or hormones.
|
|
|
What is a gial cell?
|
A cell of the nervous system that provides support and insulation for neurons.
|
|
|
What is a hair follicle?
|
A gland in the dermis of mammalian skin, formed from epithelial tissue, that produces a hair.
|
|
|
What is homeostasis?
|
The maintenance of a relatively constant environment required for the optimal functioning of cells, maintained by the coordintated activity of numerous regulatory mechanisms, including the respiratory, endocrine, circulatory, and excretory systems.
|
|
|
What is keratin?
|
A fibrous protein in hair, nails, and the epidermis of the skin.
|
|
|
what is a ligament?
|
A tough connective tissue band connecting two bones.
|
|
|
What is lymph?
|
A pale fluid, whithin the lymphatic system, that is composed primarily of interestial fluid and lymphocytes.
|
|
|
What is a membrane?
|
In multicellular organism, a continuous sheet of epithelial cells that covers the body and lines body cavities.
|
|
|
What is negative feedback?
|
A situation in which a change initiates a series of events that tend to couteract the change and restore the original state. Negative feedback in phsyiological systems maintains homeostasis.
|
|
|
What is a nerve tissue?
|
The tissue that make up the brain, spinal cord, and nerves: consists of neurons and gial cells.
|
|
|
What is a neuron?
|
A single nerve cell.
|
|
|
What is an organ?
|
A structure composed of two or more distinct tissue types that function together.
|
|
|
What is an organ system?
|
Two or more organs that work together to perform a specific function: for example, the digestion system.
|
|
|
What is positive feedback?
|
A situation in which a change initiates events that tend to amplify the origional change,
|
|
|
What is a sebaceous gland?
|
A gland in the dermis of skin, formed epithelial tissue, that produces the oily substance sebum, which lubricates th epidermis.
|
|
|
What is a skeletal muscle?
|
The type of muscle that is attatched to and moves the skeleton and is under direct, normally voluntary, control of the nervous system: also called striated muscle.
|
|
|
What is a smooth muscle?
|
The type of muscle that surtounds hollow organs, such as digestive tract, bladder, and blood vessels: normally not under voluntary control.
|
|
|
What is a synaptic?
|
A swelling at the branched ending of an axon: where the axon forms a synapse.
|
|
|
What is a tendon?
|
A tough connective tissue band connecting a muscle to a bone.
|
|
|
What is tissue?
|
A group of cells that together carry out a specific function: for example, muscle: may include extralcellular material produced by its cells.
