5 Flashcards
4 tissue types
Connective, epithelial, muscle, nervous
Two things found in all types of muscle cells/tissues
Actin and Myocin
The tissue that covers exposed surfaces, lines inner passageways and chambers, and forms glands.
Epithelial
The tissue that fills internal spaces, provides structural support to other tissues, transports materials w/in the body, stores energy reserves.
Connective
The tissue specialized for contraction. ___ of the body, heart, and ____ walls of hollow organs.
Muscle
The tissue that transports info from one to another part of the body in the form of electrical impulses.
Neural/Nervous
Tissue that: Conducts impulses from one region of the body to the other.
Nerve
Tissue that: Mostly in the brain, spinal cord, which are control centers of the nervous system
Nerve
What is the longest (LARGE) cell in our body, many of which are as long as 39”?
Neurons
What group of (SMALL) supporting cells help in repair and supply nutrients to neurons?
Neuroglia
3 types of muscle tissue:
Skeletal, cardiac, smooth
What do the 3 muscle tissue help with?
Moving materials along the digestive tract, blood in cardiovascular system, and moving the body from one place to another
Skeletal Muscle Fact: “Striated Voluntary” multi nucleated,
Located: connective tissues, neural tissue, skeletal muscles
Which muscle tissue moves or stabilizes the position of the skeleton; guards entrance and exits to the digestive, respiratory, and urinary tracts; generates heat; protects internal organs?
Skeletal Muscle
Which muscle tissue is responsible for gross body movement and locomotion?
Skeletal
Facts about which muscle tissue?: Un-branched cells of up to .3m in length called muscle fibers. Multinucleate, cannot divide.
Skeletal
Skeletal has major microfilament protein that creates muscle
Actin Myosin
DNA and RNA are located in the:
Nucleus
Cardiac Muscle facts: Also called “cardiocytes” Short, branched, striated, single nucleus, interconnected by intercalated discs. Location?
Heart
Functions of Cardiac Muscles:
Circulate blood, maintains blood (hydrostatic) pressure
Cardiac Muscle Facts: Smaller than skeletal muscles, small, 1 nucleus, branched, involuntary contraction w/in the pacemaker of cells, Actin and Myosin.
Cardiac Muscle Facts: Smaller than skeletal muscles, small, 1 nucleus, branched, involuntary contraction w/in the pacemaker of cells, Actin and Myosin.
Smooth Muscle Facts: “Unstriated Involuntary”, short spindle shaped, single central nucleus. Located:
Walls of blood vessels, digestive, respiratory, urinary, and reproductive organs.
Which type of muscle moves food, urine, and reproductive tract secretions; controls diameter of respiratory passage ways and blood vessels?
Smooth
Which muscle type is found in the walls of organs that need elasticity, contractility, and support. Unbranched, contract mostly on their own, Actin and Myosin organized differently than the other two.
Smooth
