WWU A&P Fall of 2024
Tissue Injury and Repair: Fibrosis Description
Scab falls off Scar may be visible depending on severity of tissue damage
Tissue Injury and Repair: Regeneration Description
Fibroblasts lay down temporary ECM New capillaries grow Epithelium forms new tissue layer
Tissue Injury and Repair: Inflammation Description
White blood cells, clotting factors enter damage site Clotting factors form blood clot (scab)
Nervous tissue: Neurons and Glial Cells Location
Brain Spinal Cord Cranial peripheral nerves
Nervous tissue: Glial Cells Description
Provide structural support, protection and nourishment for neurons in the brain and spinal cord
Nervous Tissue: Neurons Description
Receive sensory information and carry it to the brain Transmit motor impulses from brain to effector organs Form synapses with one another
Nervous Tissue: The two major cell major cell types are?
Nuerons Glialt cells
Muscle Tissues: Smooth Muscle Location
Walls of hollow organs
Muscle Tissues: Smooth Muscle Description
Spindle-shaped cells with central nucleus Found in layers that form sheets Can provide force (e.g. during uterine contractions) Can accomodate stretch (e.g. digestive system )
Muscle tissues: Cardiac Muscle Location
Heart wall only
Muscle Tissues: Cardiac Muscle Description
Elongated myotubes with greater degree of branching Specialized cell junctions (Intercalated discs) seen as deep red margins between cells Individual nuclei evident Striations visible Ensure flow of blood to all tissues
Muscle Tissues: Skeletal Muscle Location
Attached to bones
Muscle Tissues: Skeletal Muscle Description
Elongated myotubes formed from fused cells Multinucleated Stiations visible Funciton in voluntary skeletal movement
The three types of muscle tissue are?
Skeletal muscle Cardiac muscle Smooth muscle
Q 3.3 The human body is composed of what [four] types of tissues?
Muscle Connective Nervous Epethelial
Connective Tissue: Bone Location
Skeleton
Connective Tissue: Bone Description
Calcified collagen matrix with embedded osteocytes cross talk amoung oseteocytes
Connective Tissue: Blood Location
Contained within arteries, veins and capillaries
Connective Tissue: Blood Description
Erythrocytes, luekocytes and platelets within a plasma matrix Primary function: transport of oxygen, carbon dioxide, nutrients and other dissolved molecules throuhout the body
Connective Tissue: Blood Platelets are
Fragments of larger cells whose primary role is in the blood clotting process
