|
describe the structure of cardiac muscle
|
striated
branching cells |
|
|
describe the structure of the main types of blood vessels and relate this to their function
|
capillaries are thin walled for permeability
arteries have thick walls with a lot of elastic tissue to withstand high blood pressure arterioles have a lot of smooth muscle in the middle layer of the walls for contraction to change the diameter of the vessel to allow blood flow in a specific area of to change the blood pressure venules and veins are 3 layered but are thinner than arteries. |
|
|
name the 2 principle body cavities and outline the subdivisions of each.
|
dorsal body cavity - cranial cavity / vertebral cavity
ventral body cavity - thoracic cavity / abdominopelvic cavities |
|
|
list the four tissue types
|
epithelium - covering and lining of body surfaces and glands
connective tissue - supports and binds internal structures muscle tissue- specialised for movement nervous tissue - specialised for transmission of electrical impulses around the body |
|
|
describe the structure of a typical synovial joint and label a diagram
|
fluid filled cavity,(synovial cavity)
surrounded by a wrapping (joint capsule) the capsule is lined with a synovial membrane and is filled with synovial fluid. |
|
|
identify the nerve supply to the muscles involved in ventilation.
|
the phrenic nerve innervate the diaphragm
the intercostal nerve innervates the external intercostal muscles. |
|
|
state the 2 tubes the pharynx runs into inferiorly.
|
the eosophagus and the larynx
|
|
|
outline the difference between single and multi layered epithelia in terms of structure and function.
|
single - layered - epithelium - forms a very thin barrier, specialised for allowing the movement of materials.
multi - layered - epethilium - specialised for protection and great wear and tear. |
|
|
name the blood vessels serving the major organ systems of the body.
|
carotid arteries serve the heart
brachial and subclavian arteries serve the lungs hepactic arteries serve the liver mesentric arteries serve the abdomen femoral arteries serve the femur |
|
|
describe the structure of a muscle fibre
|
connective tissue coverings - endomysium - each fibre
perimysium - bundles of fibres epimysium - outer wrapping |
