the direct method of cell division characterized by simple division of the nucleus without formation of chromosomes
process of building up of larger molecules for smaller ones, requires energy,its a contsructive phase of cellular metabolism
In cell division, or mitosis, chromatids detach and separate to become chromosomes again 4th part of the cell cycle
loose connective tissue that binds the skin to the underlying tissues and fills the spaces between the muscles
all substances are made of subatomic particles that form these, are arranged in specific patterns and structures called molecules, molecules are arranged in such a wayas to produce compounds or matter
cardiac muscle tissue
tissues occurring in the heart, involuntary, directly stimulated by nerve impulses, pumps blood into the heart
the breaking down of larger substances or molecules into smaller ones, this process releases energy that can be stored for other reactions such as muscle contraction
a thin covering of the outer surface of a cell, or cytoplasm, transports materials from outside and inside the cell, helps to control cell activity
all chemical reactions within a cell that transforms food for cell growth and operation
structure near the nucleus with 2 rod shaped centrioles, divides in 2 parts during mitosis, helps distribute chromosomes
specialized cellular compartments, each performing its own job to maintain the life of the cell.
the process during early developmental stages, where the repeated division of the ovum results in many specialized cells that differ from one another in composition and function
found between the vertebrae and in the pubic symphasis, where strong support and limited range of motion are required
fibrous connective tissues
composed of collagen and elastin fibers that are closely arranged to form tendons and ligaments
protein substances that act as organic catalysts for chemical reactions in metabolism while remaining unchanged themselves
protective layer that functions in the process of absorption, secretion, excretion, and protection
fibrous connective tissue that forms a network throughout the body, surrounding every structure to support, seperate and give shape to the body
type of cartilage that contains little fibrous tissues made up of cells, clear or translucent , found in nose, trachea, and on the end of bones and in moveable joints
normal state of the cell,during which most of the cellular work and growth are done, chromosomes remain in thin threads, later during mitosis become rod-like
stage in cell division, or mitosis, when chromosomes arrange themselves in a plane called equitorial plane, nuclear membrane and nucleolos are absent
line the digestive and upper respitory tract to produce mucous, a thick sticky substance that acts as a protectiant and lubricant
composed of nuerons, sensitive to specifc types of stimuli, able to transmit impulses , act as channels of messages to and from the brain
groups of tissues that work together to perform a specific function or related functions or jobs
the fibrous membrane that functions to protect the bone and serves as an attachment of tendons and ligaments
the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes, stage during mitosis where chromosomes which are composed of DNA which house the genes, become larger and more defined,
colorless jelly like substance in cells in which food elements such as protein, fats, carbohydrates, mineral salts and water are present
line the body cavities and sometimes the outermost parts of the organs, produce a serous fluid, a watery substance that also act as a lubricant
are attached to bone by tendons, responsible for moving limbs, facial expression, speaking and other voluntary movements
lacks striations and can not be stimulated to contract by conscious effort, work subconsciously, work involuntarily
-Consists of many muscle fibers
-Muscle fibers consist of myofibrils
-Myofibrils give the striated look, striped looking
the final stage of meiosis or mitosis, in which the separated chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around the two sets of chromosomes
