Epithelial tissue is frequently damaged or lost by abrasion but has a ___________________
Continual replacement occurs through the divisions of the deepest epithelial cells near its base called _________________
_____________________ detect changes in the external environment.
These are continuously supplied into the nervous system.
___________________ binds body structures together
____________________ is highly variable in appearance, least specialized connective tissue in the body; loosely organized array of collagen and elastic fibers and abundant distribution of blood vessels; independent movements; found everywhere; surrounds nerves, blood vessels, and individual muscle cells; major component of the hypodermis.
_______________________ has collagen fibers packed tightly and aligned parallel to an applied force; resembles lasagna noodles stacked on each other; found in tendons and ligaments; few blood vessels(ie. takes a long time to heal[upper ear piercing]).
__________________ is the most common type of cartilage; the weakest type of cartilage; surrounded by perichondrium; forms most of the fetal skeleton and is a model for most future bone growth; is located at articular ends of long bones which allows the bones in a joint to move freely and easily; found in the nose, trachea, larynx, costal cartilage, and articular ends of long bones.
______________ is composed of cells called adipocytes; serves as packing around structures and provides padding, cushions shocks, and acts as an insulator to slow heat loss through the skin; primary energy store.
Bone is formed in cylindrical structures called _______.
________ are specialized to detect stimuli, process information quickly, and rapidly transmit electrical impulses from one region of the body to another. They are also concentrated in the brain and spinal cord, and are the control centers for the nervous system.
Each neuron has a ________ that houses the nucleus and most organelles. It also is the "head" that controls the cell and produces proteins for the cell.
Branches extend from the cell body called ___________ which receive incoming signals from other cells and transmit the info to the cell body.
The long nerve cell process extending from the cell body is the ______.
_________ are the longest cells in the body due to the length of the ________. Some are longer than a meter.
