Tissues
groups of cells that possess similar structures, shapes, and functions
Epithelial Tissue
Shape
Shape: rectangular or circular
Epithelial Tissue
Functions
Functions: protection, secretion, absorption
Epithelial Tissue
Locations
Locations: skin, linings of body cavities, arteries, veins, and other tubular structures
Muscle Tissue
Shape
Shape: long and narrow
Muscle Tissue
Functions
Functions: Contract
Muscle Tissue
Locations
Locations: heart (cardiac), attached to skeleton (skeletal), lining various organs= smooth
Nervous Tissue
Shape
Shape: highly irregular
Nervous Tissue
Functions
Functions: conduction of information
Nervous Tissue
Locations
Locations: Throughout the body, e.g. brain, spinal cord, neurons
Connective Tissue
Shape
Shape: variety
Connective Tissue
Function
Function: basically to "connect" various parts of the body
Connective Tissue
Locations
Locations: bone (bone cells), cartilage (cartilage cells), blood (blood cells), supporting cells throughout the body
Organs
large groups of cells consisting of 1 or more tissues organized into a unit which carry out a specific function
Systems
composed of several organs which have a common function or functions
Homeostasis
"maintenance of the internal environment"
Osteoblasts
form bone matrix and synthesize collagen
Osteocytes
mature bones cells
Osteoclasts
responsible for the resorption of bone
Vitamins
complex organic compounds not synthesized for the most part by human cells; most function as coenzymes and participate in ATP yielding but by themselves are worthless
Nervous System
most comprehensive and versatile system in body; influences all portions of body except epidermis of skin and cartilage; if it malfunctions it can lead to serious problems in other body systems
Central Nervous System (CNS)
includes brain and spinal cord, mid-line of body
Peripheral Nervous System (PNS)
includes the neurons of the periphery of the body; have their origin in the CNS and their branches reach to the periphery
Neuron
nerve cell, functional unit of nervous system
Autonomic Nervous System (ANS)
consists of the neurons associated with smooth and cardiac muscle and certain glands; may be included under PNS
Somatic Nervous System (SNS)
consists of neurons associated with skeletal muscle; may be included under PNS
Neurolemma
term usually referring to the plasma membrane of the Schwann call surrounding an unmyelinated axon or the outermost layer of the plasma membrane of the Schwann cell in myelinated axon
Schwann Cell
aka
Neurolemmocytes
aka
Epineurium
connective tissue surrounding a large bundle of axons in a nerve
Perineurium
connective tissue surrounding small groups of axons within a nerve
Endoneurium
connective tissue surrounding each axon in a nerve
Neuroglia
unique to CNS
role: degeneration and regeneration, "support" and/or nourishing role for CNS neurons, may be inplicated in Alzheimer's and Parkinson's
Astrocytes
star-shaped cells; largest and most numerous of neuroglia; participates in brain development and the metabolism of neurotransmitters, helps form blood-brain barrier, helps maintain the proper balance of K+, for generagtion of nerve impulses, and provides a link between neurons and blood vessels
Oligodendrocytes
supports neurons and produces a myelin sheath around axons of neurons of the CNS
Microglia
phagocytic cells, clean up debris, damaged neurons, drived from monocytes
Ependymal
line ventricles in brain
