Action potential
An action potential occurs when the membrane potential of a specific cell rapidly rises and falls.
See Reflex arc and Action potential
Ankle jerk reflex
The ankle jerk reflex, also known as the Achilles reflex, occurs when the Achilles tendon is tapped while the foot is dorsiflexed. Reflex arc and ankle jerk reflex are Reflexes.
See Reflex arc and Ankle jerk reflex
Antagonist
An antagonist is a character in a story who is presented as the main enemy and rival of the protagonist.
Anterior grey column
The anterior grey column (also called the anterior cornu, anterior horn of spinal cord, motor horn or ventral horn) is the front column of grey matter in the spinal cord.
See Reflex arc and Anterior grey column
Autonomic nervous system
The autonomic nervous system (ANS), sometimes called the visceral nervous system and formerly the vegetative nervous system, is a division of the nervous system that operates internal organs, smooth muscle and glands.
See Reflex arc and Autonomic nervous system
Axon
An axon (from Greek ἄξων áxōn, axis) or nerve fiber (or nerve fibre: see spelling differences) is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body.
Brain
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.
Central nervous system
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord.
See Reflex arc and Central nervous system
Chemical synapse
Chemical synapses are biological junctions through which neurons' signals can be sent to each other and to non-neuronal cells such as those in muscles or glands.
See Reflex arc and Chemical synapse
Crayfish
Crayfish are freshwater crustaceans belonging to the infraorder Astacidea, which also contains lobsters.
Glutamic acid
Glutamic acid (symbol Glu or E; the anionic form is known as glutamate) is an α-amino acid that is used by almost all living beings in the biosynthesis of proteins.
See Reflex arc and Glutamic acid
Glycine
Glycine (symbol Gly or G) is an amino acid that has a single hydrogen atom as its side chain.
Hamstring
In human anatomy, a hamstring is any one of the three posterior thigh muscles between the hip and the knee (from medial to lateral: semimembranosus, semitendinosus and biceps femoris).
Interneuron
Interneurons (also called internuncial neurons, relay neurons, association neurons, connector neurons, intermediate neurons or local circuit neurons) are neurons that connect to brain regions, i.e. not direct motor neurons or sensory neurons.
See Reflex arc and Interneuron
Lateral giant interneuron
The lateral giant interneuron (LG) is an interneuron in the abdominal nerve cord of crayfish, lobsters, shrimp of the order Decapoda and their relatives in the crustacean class Malacostraca.
See Reflex arc and Lateral giant interneuron
Lazarus sign
The Lazarus sign or Lazarus reflex is a reflex movement in brain-dead or brainstem failure patients, which causes them to briefly raise their arms and drop them crossed on their chests (in a position similar to some Egyptian mummies). Reflex arc and Lazarus sign are Reflexes.
See Reflex arc and Lazarus sign
Motor nerve
A motor nerve, or efferent nerve, is a nerve that contains exclusively efferent nerve fibers and transmits motor signals from the central nervous system (CNS) to the muscles of the body.
See Reflex arc and Motor nerve
Motor system
The motor system is the set of central and peripheral structures in the nervous system that support motor functions, i.e. movement.
See Reflex arc and Motor system
Muscle spindle
Muscle spindles are stretch receptors within the body of a skeletal muscle that primarily detect changes in the length of the muscle.
See Reflex arc and Muscle spindle
Neural pathway
In neuroanatomy, a neural pathway is the connection formed by axons that project from neurons to make synapses onto neurons in another location, to enable neurotransmission (the sending of a signal from one region of the nervous system to another).
See Reflex arc and Neural pathway
Neurotransmitter
A neurotransmitter is a signaling molecule secreted by a neuron to affect another cell across a synapse.
See Reflex arc and Neurotransmitter
Patellar reflex
The patellar reflex, also called the knee reflex or knee-jerk, is a stretch reflex which tests the L2, L3, and L4 segments of the spinal cord. Reflex arc and patellar reflex are Reflexes.
See Reflex arc and Patellar reflex
Patellar tendon
The patellar tendon is the distal portion of the common tendon of the quadriceps femoris, which is continued from the patella to the tibial tuberosity.
See Reflex arc and Patellar tendon
Posterior grey column
The posterior grey column (posterior cornu, dorsal horn, spinal dorsal horn, posterior horn, sensory horn) is one of the three grey columns of the spinal cord.
See Reflex arc and Posterior grey column
Quadriceps
The quadriceps femoris muscle (also called the quadriceps extensor, quadriceps or quads) is a large muscle group that includes the four prevailing muscles on the front of the thigh.
Reflex
In biology, a reflex, or reflex action, is an involuntary, unplanned sequence or action and nearly instantaneous response to a stimulus. Reflex arc and reflex are Reflexes.
Sensory nerve
A sensory nerve, or afferent nerve, is an anatomic term for a nerve that contains exclusively afferent nerve fibers.
See Reflex arc and Sensory nerve
Sensory nervous system
The sensory nervous system is a part of the nervous system responsible for processing sensory information.
See Reflex arc and Sensory nervous system
Sensory neuron
Sensory neurons, also known as afferent neurons, are neurons in the nervous system, that convert a specific type of stimulus, via their receptors, into action potentials or graded receptor potentials.
See Reflex arc and Sensory neuron
Somatic nervous system
The somatic nervous system (SNS) is made up of nerves that link the brain and spinal cord to voluntary or skeletal muscles that are under conscious control as well as to skin sensory receptors.
See Reflex arc and Somatic nervous system
Spinal cord
The spinal cord is a long, thin, tubular structure made up of nervous tissue that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column (backbone) of vertebrate animals.
See Reflex arc and Spinal cord
Synapse
In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell.
Vertebrate
Vertebrates are deuterostomal animals with bony or cartilaginous axial endoskeleton — known as the vertebral column, spine or backbone — around and along the spinal cord, including all fish, amphibians, reptiles, birds and mammals.
