31.1
All Cells in the Body are made out of Stem Cells, which can divide or differecentate into differecnt cell types
The First divisons of a Feeritlized Egg, yeild Totipotent cells that can any tissue or develop into an individual
Later, Embryos have pluripotent cells that still form any tissue
Scientits hope to use these stem cells, to produce cells that
would not be naturaly replaced in adults
After Birth, cells become less versitile
31.5
Contraction Muscule Tissue Moves the Body. This is a response form the nervous system and is fuled by ATP
Cardiac Muscle Tissue, found only in the heart, its cells are branced and have a signle nucleus
-
Smooth Muscle Tissue, found in the walls of tubular organs and blood vessels. Unbranched cells, single nucleus,not straited
-
-
31.2
-
Physical, Developmental Factors and evolutionary history constrain anmal body plans
31.4
Connective tissuess, bind, organize, support, trengthen, protect and insulate other tissues.
-
Losse and Connective tissues have the same componentes, in differnet proportions
-
-
Fat, which is stored in the adipose tissue, is the main resivoir of energy in the body
-
Blood is made up of: Fluid Plasma, Cells and Platelets. Its Considered Connective Tissue because blood cells and platelets are formed in bone marrow
31.6
Nervous Tissue isthe communication system in the body and it´s found in the brain, spinal cord, and nerves.
They consist of Neurons that send and recive communication signals and glial cells that support them.
-
Sensory Neurons detect information
Interneurons intergrane and asses information about internal and external conditions
Motor Neurons command the muscles and glands.
