Excitation Contraction Coupling
|
D056966 |
[A process fundamental to muscle physiology whereby an electrical stimulus or action potential triggers a myocyte to depolarize and contract. This mechanical muscle contraction response is regulated by entry of calcium ions into the cell.

|
Excitatory Amino Acid Agents
|
D018683 |
[Drugs used for their actions on any aspect of excitatory amino acid neurotransmitter systems. Included are drugs that act on excitatory amino acid receptors, affect the life cycle of excitatory amino acid transmitters, or affect the survival of neurons using excitatory amino acids.

|
Excitatory Amino Acid Agonists
|
D018690 |
[Drugs that bind to and activate excitatory amino acid receptors.
] |
|
Excitatory Amino Acid Antagonists
|
D018691 |
[Drugs that bind to but do not activate excitatory amino acid receptors, thereby blocking the actions of agonists.

Excitatory Amino Acid Transporter 1
|
D027341 |
[A glial type glutamate plasma membrane transporter protein found predominately in ASTROCYTES. It is also expressed in HEART and SKELETAL MUSCLE and in the PLACENTA.
] |
|
Excitatory Amino Acid Transporter 2
|
D027342 |
[A glutamate plasma membrane transporter protein found in ASTROCYTES and in the LIVER.
] |
|
Excitatory Amino Acid Transporter 3
|
D050580 |
[A neuronal and epithelial type glutamate plasma membrane transporter protein.
] |
|
Excitatory Amino Acid Transporter 4
|
D050581 |
[A glutamate plasma membrane transporter protein that is primarily expressed in cerebellar PURKINJE CELLS on postsynaptic DENDRITIC SPINES.
] |
|
Excitatory Amino Acid Transporter 5
|
D050582 |
[A glutamate plasma membrane transporter protein that is primarily expressed in the RETINA.
] |
|
Excitatory Amino Acids
|
D018846 |
[Endogenous amino acids released by neurons as excitatory neurotransmitters. Glutamic acid is the most common excitatory neurotransmitter in the brain. Aspartic acid has been regarded as an excitatory transmitter for many years, but the extent of its role as a transmitter is unclear.

|
Excitatory Postsynaptic Potentials
|
D019706 |
[The flow of ions into or out of cells that cause EXCITATORY POSTSYNAPTIC POTENTIALS.
, Depolarization of membrane potentials at the SYNAPTIC MEMBRANES of target neurons during neurotransmission. Excitatory postsynaptic potentials can singly or in summation reach the trigger threshold for ACTION POTENTIALS.
, Excitatory postsynaptic potentials at the NEUROMUSCULAR JUNCTION.

|
Executive Function
|
D056344 |
[A set of cognitive functions that controls complex, goal-directed thought and behavior. Executive function involves multiple domains, such as CONCEPT FORMATION, goal management, cognitive flexibility, INHIBITION control, and WORKING MEMORY. Impaired executive function is seen in a range of disorders, e.g., SCHIZOPHRENIA; and ADHD.

|
Exenatide
|
D000077270 |
[A synthetic form of exendin-4, a 39-amino acid peptide isolated from the venom of the Gila monster lizard (Heloderma suspectum). Exenatide increases CYCLIC AMP levels in pancreatic acinar cells and acts as a GLUCAGON-LIKE PEPTIDE-1 RECEPTOR (GLP-1) agonist and incretin mimetic, enhancing insulin secretion in response to increased glucose levels; it also suppresses inappropriate glucagon secretion and slows gastric emptying. It is used an anti-diabetic and anti-obesity agent.

|
Exercise
|
D015444 |
[Physical activity which is usually regular and done with the intention of improving or maintaining PHYSICAL FITNESS or HEALTH. Contrast with PHYSICAL EXERTION which is concerned largely with the physiologic and metabolic response to energy expenditure.
, A single bout of exercise.
] |
|
Exercise Movement Techniques
|
D026241 |
[A form of exercise, based on the teachings of Joseph Pilates (1880-1967), redesigned for rehabilitation after musculoskeletal injuries. It focuses on body mechanics, posture, and strengthening of the core (back and abdominal) muscles.
, Methods or programs of physical activities which can be used to promote, maintain, or restore the physical and physiological well-being of an individual.
] |
|
Exercise Test
|
D005080 |
[A set of nine physical fitness tests for flexibility, speed, endurance and strength developed by the Council of Europe for school age children and adults. The tests are performed within 35 to 40 minutes using very simple equipment.
, Controlled physical activity which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used.
] |
|
Exercise Therapy
|
D005081 |
[A regimen or plan of physical activities designed and prescribed for specific therapeutic goals. Its purpose is to restore normal musculoskeletal function or to reduce pain caused by diseases or injuries.
] |
|
Exercise Tolerance
|
D017079 |
[The exercise capacity of an individual as measured by endurance (maximal exercise duration and/or maximal attained work load) during an EXERCISE TEST.
] |
|
Exfoliatins
|
D005083 |
[Protein exotoxins from Staphylococcus aureus, phage type II, which cause epidermal necrolysis. They are proteins with a molecular weight of 26,000 to 32,000. They cause a condition variously called scaled skin, Lyell or Ritter syndrome, epidermal exfoliative disease, toxic epidermal necrolysis, etc.
] |
|
Exfoliation Syndrome
|
D017889 |
[The deposition of flaky, translucent fibrillar material most conspicuous on the anterior lens capsule and pupillary margin but also in both surfaces of the iris, the zonules, trabecular meshwork, ciliary body, corneal endothelium, and orbital blood vessels. It sometimes forms a membrane on the anterior iris surface. Exfoliation refers to the shedding of pigment by the iris. (Newell, Ophthalmology, 7th ed, p380)
