Day 7 - Tissues Flashcards
It is composed of groups of similar cells that perform a specific function.
Tissues
It has 1 cell and it is classified as the lower forms
Unicellular Organism
It is composed of multiple number of cells. It is at the higher form of cell
Multicellular
What are the animal tissues?
Epithelial tissues
Muscular
Connective
Nervous
It is an animal tissue that covers body’s internal and external forces. It is for protection, nutrient absorption and secretion.
Epithelial tissue
What are the epithelium cells that are classified by the number of its layers?
Simple and Stratified
What is the difference between simple and stratified epithelium?
Simple has only 1 stack of cells while stratified has 2 or more stacks.
What are the different epithelium tissues according to its shape?
Squamous, Cuboidal, Columnar, Ciliated
What are the difference between Squamous, Cuboidal, Columnar, Ciliated?
Squamous - flattened
Cuboidal - cube
Columnar - tall and thin
Ciliated - either columnar or cuboidal
It has single layer of flat cells with oval nuclei. It is located at the lungs or blood vessels because it has an easy way for oxygen to pass through.
Simple Squamous Epithelium
It is roughly cuboidal and has spherical nucleus. It is secretive and adaptive
Simple cuboidal epithelium
It is elongated with elongated nuclei. It has a sensory perception and it is also absorptive
Simple Columnar
It is the tissue that is responsible for contraction and movement.
Muscular Tissue
It is elongated and arranged in parallel ways and it is composed of cytoplasm, sarcoplasm and sarcolemma
Muscle Fiber
Myofibril has 2 contractile proteins called?
Actin and Myosin
What are the different muscle tissues based on location?
Skeletal, Visceral/Smooth, Cardiac
This muscular tissue is attached to the bones.
Skeletal Tissue
This tissue is found at the walls of hollow internal structures.
Visceral/ Smooth
This muscular tissue is found in the heart. It contracts and pumps blood.
Cardiac muscles
What are the muscular tissue based on appearance?
Striated and unstriated
What is striated and unstriated?
Striated has cross striations while unstriated has none
What are the muscle tissue based on neural control?
Voluntary and Involuntary Muscles
What is the difference between voluntary and involuntary muscles?
Voluntary is found outside of the skeleton and it is controlled by a person
Involuntary is not controlled and it is usually internal organs
It has a long filament with many elongated nuclei. It also has many striations of the dark and light cross bands
Skeletal Muscle
It is a spindle shaped cell found in the walls of visceral organs and it has no striations.
Smooth Tissue
It is striated and involuntary. It has a lot of nuclei and has cross striation and unique dark bands.
Cardiac muscle
It binds together various parts of the body to give form and support. It is characterized by the presence of extracellular matrix. (It is the most diverse and abundant tissue)
Connective Tissue
It is a non living material composed of protein fibers and ground substance
Extracellular Matrix
This has a lot of starchy strands called glycosaminoglycans or GAGs and it gives strength and flexibility
Protein fibers
It supports the cells and fibers. It is also where cartilage, bone tendon, ligament and adipose tissue are found
Ground substance
What are the types of protein fibers?
Collagen, Elastic Fiber, Reticular
It is a protein fiber that is strong
Collagen
It is a protein fiber that is thinner and can be stretched.
Elastic Fiber
It is a protein fiber that is finer than collagen and its spongy
Reticular
What are the kinds of connective tissue?
Proper connective tissue
Cartilage
Bone/Osseous Tissue
Blood/Vascular Tissue
It is a type of proper connective tissue that is loosely arranged fibro-elastic tissue. It has amorphous ground substance with hold coagulable tissue fluids. It binds muscle and fills space between organs.
Loose or Areolar connective tissue
It is tightly packed collagen. example is a tendon. What type of Proper connective tissue is this.
Dense connective tissue
This is a proper connective tissue that has clear oval cells for insulation and fuel storage. The nucleus are pushed to the side by a globule.
Adipose or Fat tissue
This is found at the ends of long bones and ribs. It is bluish white and it is rich in GAGs. It is more common than fibrous elastic cartilage
Hyaline Cartilage
Hyal = glass (bluish white)
It has cartilage cells and has lacunae or small cavities. It is also scattered through the chondrin matrix
Chondrocytes
It is a dense organic matrix and it has mineral deposit of calcium carbonate and tricalcium phosphate.
Bone or Osseous Tissue
What are the 2 types of bone tissues?
Compact bone and spongy or calcareous bones
It is a bone tissue that is solid and found externally. It is dense and has no space in between.
Compact Bone
It is a bone tissue that is composed of lattice work of short bars and plate. It is found internally
Spongy Or Calcareous Bone Tissue
What are the parts of the bone?
Lamella Periosteum Haversian System Lacunae Canaliculi
It is a part of the bone tissue that has thin layer where other non living mineral substances are deposited
Lamella
It is the outermost covering of the bones and it is where muscles and tendons are attached.
Periosteum
It is a part of the bone that longitudinally providing channels for blood vessels
Haversian System
It is small spaces found in the bone cell
Lacunae
It composed of fine radiating canals that connects bone cell with adjacent cells
Canaliculi
It is composed of cells and extracellular matrix. It is also a tissue for transporting nutrients all over your body
Blood or vascular tissue
It is a fluid substance where specialized cells are embedded.
Plasma
What are the types of blood cells?
RBC WBC and Thrombocytes
It has numerous disk shaped cells with no nuclei. The red color is because of the hemoglobin and it is used for transporting oxygen and carry waste materials
RBC
It is lesser in number and bigger in size. It is used in the immune system
WBC
It is the smallest WBC with large rounded nuclei
Lymphocytes
It is the largest WBC and it is centrally places nucleus shaped like a kidney
Monocytes
It is the granules found in the cytoplasm and it is also called as neutrophil (most numerous WBC) that has 3 or more lobes
Granulocytes
I has 2 oval lobes connected by thin chromatin thread and basophil
Eosinophile
It is a type of blood cell that is responsible for blood clotting and it is also known as Platelets (an annucleated cell fragments)
Thrombocytes
It is a type of animal tissue that controls and is responsible for communication. It transmits stimuli and exhibits irritability
Nervous system
It is a cell body containing the nucleus and cytoplasmic extension dendrite)
Neuron
IT carries impulse towards the cell body
Dendrite
It is a nucleated cell membrane that covers the axon cylinder
Myelin Shath
It supports, nourishes and protects neurons. It is capable of mitosis
Neuroglia or Nerve Glue
