Standard anatomical terms of location deal unambiguously with the anatomy of animals, including humans.
The basal ganglia (or basal nuclei) is a group of subcortical nuclei, of varied origin, in the brains of vertebrates including humans, which are situated at the base of the forebrain.
The brainstem (or brain stem) is the posterior part of the brain, adjoining and structurally continuous with the spinal cord.
The cerebral aqueduct, also known as the aqueductus mesencephali, mesencephalic duct, sylvian aqueduct or the aqueduct of Sylvius is within the mesencephalon (or midbrain), contains cerebrospinal fluid (CSF), and connects the third ventricle in the diencephalon to the fourth ventricle within the region of the mesencephalon and metencephalon, located dorsal to the pons and ventral to the cerebellum.
The cerebral cortex is the largest region of the cerebrum in the mammalian brain and plays a key role in memory, attention, perception, cognition, awareness, thought, language, and consciousness.
The cerebral crus (crus cerebri) is the anterior portion of the cerebral peduncle which contains the motor tracts, the plural of which is cerebral crura.
The dorsal nucleus of the vagus nerve (or posterior motor nucleus of vagus) is a cranial nerve nucleus for the vagus nerve in the medulla that lies ventral to the floor of the fourth ventricle.
An embryo is an early stage of development of a multicellular diploid eukaryotic organism.
A fetus is a stage in the prenatal development of viviparous organisms.
Homeostasis is the tendency of organisms to auto-regulate and maintain their internal environment in a stable state.
Latin (Latin: lingua latīna) is a classical language belonging to the Italic branch of the Indo-European languages.
The medulla oblongata (or medulla) is located in the brainstem, anterior and partially inferior to the cerebellum.
The midbrain or mesencephalon (from Greek mesos 'middle', and enkephalos 'brain') is a portion of the central nervous system associated with vision, hearing, motor control, sleep/wake, arousal (alertness), and temperature regulation.
A neural pathway is the connection formed by axons that project from neurons to make synapses onto neurons in another location, to enable a signal to be sent from one region of the nervous system to another.
In the developing chordate (including vertebrates), the neural tube is the embryonic precursor to the central nervous system, which is made up of the brain and spinal cord.
A neuron, also known as a neurone (British spelling) and nerve cell, is an electrically excitable cell that receives, processes, and transmits information through electrical and chemical signals.
Neurotransmitters are endogenous chemicals that enable neurotransmission.
The oculomotor nerve is the third cranial nerve.
The periaqueductal gray (PAG, also known as the central gray) is the primary control center for descending pain modulation.
The pons (Latin for "bridge") is part of the brainstem, and in humans and other bipeds lies inferior to the midbrain, superior to the medulla oblongata and anterior to the cerebellum.
The red nucleus or nucleus ruber is a structure in the rostral midbrain involved in motor coordination.
A reflex, or reflex action, is an involuntary and nearly instantaneous movement in response to a stimulus.
The reticular formation is a set of interconnected nuclei that are located throughout the brainstem.
In the human brainstem, the solitary nucleus (SN) (nucleus of the solitary tract, nucleus solitarius, nucleus tractus solitarii) is a series of purely sensory nuclei (clusters of nerve cell bodies) forming a vertical column of grey matter embedded in the medulla oblongata.
The substantia nigra (SN) is a basal ganglia structure located in the midbrain that plays an important role in reward and movement.
The superior colliculus (Latin, upper hill) is a paired structure of the mammalian midbrain.
The tectum (Latin: roof) is a region of the brain, specifically the dorsal (top) part of the midbrain (mesencephalon).
The ventral tegmental area (VTA) (tegmentum is Latin for covering), also known as the ventral tegmental area of Tsai, or simply ventral tegmentum, is a group of neurons located close to the midline on the floor of the midbrain.
The ventricular system is a set of four interconnected cavities (ventricles) in the brain, where the cerebrospinal fluid (CSF) is produced.
