Q

What are the two types of Neurons and what are their functions?

A

Motor (efferent) Neurons - recieve signals from the Movement Control Centres of the brain via the spinal cord and transmit them to the movement effector organs, Sensory (afferent) Neurons - sense changes in the internal or external environment and transmit signals to the brain via the spinal cord.

Q

What is a Node of Ranvier?

A

The Node of Ranvier is the gap between the glial cells of the myelin sheath. These glial cells are called Schwann cells, and they help to electrically insulate the neuron.

Q

What is a Myelin Sheath?

A

Myelin is an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord. It is made up of protein and fatty substances.

Q

Describe the circulation of De-oxygenated Blood through the Heart.

A

Blood enters the relaxed right Atrium from the Superior and Inferior Vena Cava. When the Sinoatrial (SA) Node is activated, the Atriums contract, forcing blood from the Right Atrium into the relaxed Right Ventricle through the Tricuspid Valve. The electrical impulse arrives at the Atrioventricular (AV) Node, which delays the transmission for 100ms whilst the Right Ventricle fills with blood. The Bundles of His (Purkinje Fibres carry the impulse to the Heart Apex. The impulse spreads across the Ventricles causing them to contract, forcing blood out of the Right Ventricle into the Pulmonary Arteries through the Pulmonary Valve.

Q

Describe the circulation of Oxygenated Blood through the Heart.

A

Blood enters the relaxed left Atrium from the Pulmonary Vein. When the Sinoatrial (SA) Node is activated, the Atriums contract, forcing blood from the Left Atrium into the relaxed Left Ventricle through the Mitral Valve. The electrical impulse arrives at the Atrioventricular (AV) Node, which delays the transmission for 100ms whilst the Left Ventricle fills with blood. The Bundles of His (Purkinje Fibres carry the impulse to the Heart Apex. The impulse spreads across the Ventricles causing them to contract, forcing blood out of the Left Ventricle into the Aorta through the Aortic Valve.

Q

What are the five functions of the Skeletal System?

A

Provide a framework of support for the body, Protection – connective tissue which forms boundaries of the cranium, thorax and pelvis, Movement & Posture– Form joints with leverage that are moved by muscle, Haematopoiesis – production of blood cells Storage and homeostasis

22
Q

Name all of the bones of the leg from the Sacrum to the toes.

A

Illium, Pubis, Ischium, Femur, Patella, Tibia, Fibula, Tarsels, Metatarsels, Phalanges

23
Q

Name all of the bones of the arm from the Acromioclavicular joint to the fingertips.

A

Humerus, Radius, Ulna, Carpels, Metacarpels, Phalanges

24
Q

What are the three types of joint?

A

Fibrous joint, Synovial joint, Cartilaginous joint

25
Q

What is the filtration path of urine through the Kidney?

A

Nephron, Collecting duct, Papillary duct, Minor Calyx, Major Calyx, Renal Pelvis, Ureter, Urinary Bladder

26
Q

From entry to exit, what is the path of fluids filtered through the Nephron?

A

Blood enters via the Glomerulus. Plasma travels through the Bowman’s Capsule, Proximal Convoluted Tubule, Loop of Henle, Distal Convoluted Tubule, and into a collecting duct

27
Q

What is the path of Urine through the Bladder?

A

Urine enters through the Ureteral Openings from the Ureters. It is held in the Bladder by the Internal Urethral Sphyncter. When the Bladder fills, stretch receptors in the lining of the Bladder send a signal to the brain, giving the urge to urinate. The internal urethral sphyncter relaxes, and the Detrusor Muscle contracts. The external Urethral Sphyncter relaxes voluntarily, allowing urine to pass into the Urethra and out of the body.

28
Q

What is the path of Oxygen (and other gases at first) through the respiratory tract and into Circulation?

A

Nasal Cavity/Oral Cavity, Nasopharynx/Oropharynx, Laryngopharynx, Tranchea, Bronchi (left and right), Bronchioles, Alveoli, Venules, Pulmonary Veins

Q

What are the 8 components of the Alimentary Canal?

Mouth, Pharynx, Esophagus, Stomach, Small Intestine, Large Intestine, Rectum, Anus

30
Q

What are the 9 functions of the GI Tract?

A

Ingestion, Deglutition, Secretion, Mixing and propulsion (Peristalsis), Digestion – Mechanical & chemical, Absorption, Metabolism, Synthesis, Defecation

31
Q

What are the four layers of the Gastrointestinal Tract?

A

Serosa, Connective tissue (Epithelium, Muscle -Circular -Longitudinal), Submucosa, Mucosa (modifications occur associated with specialised functions eg villi)

32
Q

Which organ connects the Oesophagus with the Duodenum?

A

Stomach

38
Q

What is Maltase?

A

An enzyme that converts disaccharide Maltose into monosaccharides (2 x Glucose)

Q

What is Lipase?

A
