TISSUES

Organising Cells Into Tissues

QUESTIONANSWER
TISSUE Types ? EPITHELIAL, CONNECTIVE, MUSCULAR & NERVOUS.
EPITHELIAL Tissue ? SKIN (the Epithelium). A continuous sheet that covers the entire body in addition to lining the bodys Cavitys.
Epithelial, PROTECTIVE ? Keeps the body from Losing Moisture & Drying out. Protects against Injury to Internal Structures. Helps guard against Bacterial Invasion.
EPITHELIUM in the STOMACH ? Lines & Protects the Stomach, which Prodeuces Enzymes & Acids that would Destroy the Stomach if it weren't for the Epithelium's Mucus Secreations.
EPITHELIUM in the NASAL CAVITY ? Contains Hairy Projections called CILLIA, which Trap Dirt & other Particles to keep them from getting down your Lungs.

Epithelial, Stratified Squamous Epithelium ? Is in the outer layer of SKIN.
Epithelial, Pseudostratified Columnar Epithelium ? Found in the Glands & Organs that Secreate Products, such as in the Digestive Tract.
Epithelial, CILIATED ? Meaning having CILIA.
Epithelial, Pseudostratified CILIATED Columnar Epithelium ? This type of Tissue is found in the lining of the NOSE & TRACHEA (Windpipe) & the Product it Secreats is Mucus.
CONNECTIVE TISSUE ? Difficult Tissue to Visualize because it has so MANY Functions & thus MANY Different Forms.
Connective Tissue, SOME VARIUOS FUNCTIONS ? In the BONES is Suportive & Provides PROTECTION. In other parts of the Body, Connective Tissue fills in Spaces & Stores Fat to Provide the Body with what Amounts to SHOCK Absorbers, Also Produces Blood Cells.
Connective Tissue, MADE UP OF ? Generally of Cells that are Spaced Far Apart with a Fluid or Gel-Like MATRIX.
Connective Tissue, MATRIX ? The MAT / Grid that Holds the CELLS (Which may be Far Apart) Together.
Connective Tissue, Matrix, TISSUE TYPES ? WHITE, YELLOW & RECTICULAR.
Connective Tissue, Matrix, Tissue WHITE ? Fibres contain the STRONG & STREtchy Protien called COLLAGEN.
Connective Tissue, Matrix, Tissue YELLOW ? Fibres contains the More STRETCHY (Elastic) but WEAKER Protein called ELASTIN.
Connective Tissue, Matrix, Tissue RETICULAR ? Fibres are Really THIN, Extreamely BRANCHED Fibres that Provide Support.
Connective Tissue, 2 TYPES OF CONNECTIVE TISSUE ? LOOSE & FIBROUS.
Connective Tissue, LOOSE ? Holds Structures Together, e.g. Holds the Outer Layer of Skin to the Underlying Muscle Tissue, Or the Intestines to the Outer Wall of the Abdominal Cavity.
Connective Tissue, LOOSE, Made Up Of ? Cells calle FIBROBLASTS, Which are Large & Shaped like Stars.
Connective Tissue, LOOSE, FIBROBLASTS ? In Loose Connect Tissue, FIBROBLASTS are Spaced Far Apart & the MATRIX Spread amoung the Fibroblasts Contains both Collagen & Elastin Fibres.
Connective Tissue, LOOSE, 2 Types of Fibres ? ADIPOSE Tissue & LYMPHOID Tissue.
Connective Tissue, LOOSE, ADIPOSE Tissue ? FAT, Has Fibroblast-like Adipose Cells that get Larger as they fill with LIPIDS (Fat), Eventually limiting the Collegen & Elastin Fibres in the Matrix.
Connective Tissue, LOOSE, ADIPOSE / FAT Advantages ? Fat Insulates the Body, Protects the Internal Organs & provides a Source of Energy when Needed.
Connective Tissue, LOOSE, ADIPOSE / FAT DISADVANTAGE ? BEER GUT ?
Connective Tissue, LOOSE, LYMPHOID Tissue ? Found in the LYMPH Nodes., SPLEEN TYHMUS GLAND & RED BONE MARROW.
Connective Tissue, LOOSE, LYMPHOID Tissue, All Involved In ? The IMMUNE FUNCTIONS.
Connective Tissue, LOOSE, LYMPHOID Tissue, Made Up Of ? Has Cells like Fibroblasts Except they're called RETICULAR CELLS.
Connective Tissue, LOOSE, LYMPHOID Tissue, MATRIX ? Is Filled with RETICULAR FIBRES instead of Collagen & Elastin.
Connective Tissue, LOOSE, LYMPHOID Tissue, MATRIX, RETICULAR FIBRES ? Reticular Fibres are those THIN, Branched Fibres that form Networks. Think of Delicate Lace.
Connective Tissue, FIBROUS. Also Holds body Parts Together, But it's Structure is a bit more RIGID than Loose Connective Tissue.
Connective Tissue, FIBROUS, MADE UP OF ? The Fibroblasts are TIGHTLY Packed & the matrix contains Collagen Fibres that run PARALLEL to each other.
Connective Tissue, FIBROUS, FOUND IN ? LIGAMENTS, Which Attach 1 bone to Another at a Joint & in TENDONS, Which Attach Muscles to Bones.
Connective Tissue, FIBROUS, CARTILAGE ? Is Stronger than Ligaments & Tendons as it's Matrix is more Solid (not as Solid as Bone), Flexes Slightly, If it Flexes too far it Breaks, Has no Blood Supply so Heals Extreamely Slowly.
Connective Tissue, FIBROUS, CARTILAGE 3 TYPES ? ELASTIC, FIBROUS & HYALINE CARTILAGE.
Connective Tissue, FIBROUS, ELASTIC CARTILAGE ? Has Many Collagen Fibres in addition to Many Elastin Fibres. Flexible & Rarely Breaks. (1 place Found in the Outer ear).
Connective Tissue, FIBROUS, FIBROUS Cartilage ? Has Mostly Collegen Fibres. It's Strong & ABSORBS SHOCK. Used to Reduce Friction between Joints.(Found between the Vertebrae in the back bone & in the Knee Joints)
Connective Tissue, FIBROUS, HYALINE Cartilage ? Contains Only Collagen Fibres. It's Strong & is the most Common from of Cartilage found in the body. Looks Smooth, White & Opaque.
Connective Tissue, FIBROUS, HYALINE Cartilage, FOUND IN ? The NOSE, In the Rings that Support the TRACHEA & at the Ends of LONG BONES (Such as Arms, Legs & Ribs).
Connective Tissue, FIBROUS, HYALINE Cartilage, FETUS ? Fetal Skeletons form from Hyaline Cartilage, which is later replaced with Bone.
Connective Tissue, FIBROUS, BONES ? Are made up of the STRONGEST Fibrous Connective tissue there is.
Connective Tissue, FIBROUS, BONE MATRIX ? Is Extremely HARD because it Contains MINERAL SALTS Mixed in with Protein Fibres. CALCIUM is the most Prevalent of the Mineral Salts found in Bone.
MUSCLE TISSUE ? Made up of MYOFIBRILS, Which are the Parts of the Fibre that Actually CONTRACT.
Muscle Tissue, 3 TYPES ? CARDIAC, SMOOTH & SKELETAL.
Muscle Tissue, STRIATED ? The Perfect Alignment of Myofibrils in the Fibre makes Muscle Tissue look Striped or Grainy.
Muscle Tissue, CARDIAC ? Of the Heart.
Muscle Tissue, CARDIAC, MADE UP OF ? Are STRIATED, CYLINDRICAL in Shape & Branched like a Tree. Large Fibres Branch of into Smaller Fibres.
Muscle Tissue, CARDIAC, NUCLEUS ? muscle Fibres in the Heart have just 1 NUCLEUS, Therefore they're Refered to as being UNINUCLEATED.
Muscle Tissue, CARDIAC, CONTRACTIONS ? A Contraction of the Heart Muscle must Spread Quickly throoughout the Heart, so the Cardiac Muscle Fibres are Interlocked. Between Contractions the Fibres in the Heart Muscle Relax Compleately so that the Muscle does not get Fatigued.
Muscle Tissue, CARDIAC, WORKS ? INVOLUNTARY. It Occurs without the need for Conscious Control.
Muscle Tissue, SMOOTH MUSCLE TISSUE ? Found in the WALLS of Hollow Internal ORGANS, Such as the STOMACH, BLADDER, INTESTINES & LUNGS.
Muscle Tissue, SMOOTH MUSCLE TISSUE, MADE UP OF ? Fibres in this type of Muscle Tissue are Uninucleated & Shaped like SPINDLES. Aranged in Paallel Lines & Form SHEETS of Muscle Tissue.
Muscle Tissue, SMOOTH MUSCLE TISSUE, CONTRACTIONS ? Is INVOLUNTARY (like Cardiac). Occurs SLOWLY & stays Contracted LONGER than Skeletal Muscle Tissue. Does not Fatigue Easily.
Muscle Tissue, SKELETAL MUSCLE TISSUE ? Found in the ARMS,LEGS & TORSO.

Muscle Tissue, SKELETAL MUSCLE TISSUE, LENGTH ? Run the Length of the ENTIRE Muscle, so can be pretty long (like the Hamstring in the back of the Thigh).
Muscle Tissue, SKELETAL MUSCLE TISSUE, CONTROL ? Under CONSCIOUS (Voluntary) Control.
NERVOUS TISSUE ? Which is responsible for COORDINATING the ACTIVITIES & MOVEMENTS OF THE BODY.
Nervous Tissue, PRESENT IN ? BRAIN, SPINAL CORD & NERVES.
Nervous Tissue, MADE UP OF ? Nerve Cells called NEURONS.
Nervous Tissue, NEURONS ? Are a Special type of Cell, Send & Recive ELECTRICAL IMPULSES.
Nervous Tissue, NEURONS, RESPOND TO ? HEAT, COLD, PAIN, TOUCH etc.
Nervous Tissue, NEURONS, ACTIVITY e.g. ? When Hormons should be released. Involuntary Actions like Smooth or Cardiac Muscle Contraction.
Nervous Tissue, NEURON CELLS ? Provide Suport, NEUROGLIAL CELLS Protect & Provide Nutrients to the Nerons
Nervous Tissue, NEURON, MADE UP OF ? a Nerve Cell Body, Which contains a Nucleus & Organelles.
Nervous Tissue, NEURON, DENTRITES ? Branch of the nerve Cell Body & they Act like Little Antennae in that they Recive Signals from Other Cells.
Nervous Tissue, NEURON, AXON ? A Long Thin Fibre, Lies at the other end of the Nerve cell Body. Has Branches at it's End that Send Signals.
Nervous Tissue, NEURON, WHICH END DOES WHAT ? Remember that the AXON "acts on" a Signal by Sending an Impulse, A DENTRITE Doesn't Send, it Recives. Remember that "dend" as in Dendrite stands for "doesn't Send.
UNINUCLEATED ? Have ONE Nuclei.
MULTINUCLEATED ? Have MANY Nuclei
