Epeirogenic movement can be permanent or transient. Transient uplift can occur over a thermal anomaly due to convecting anomalously hot mantle , and disappears when convection wanes. Permanent uplift can occur when igneous material is injected into the crust , and circular or elliptical structural uplift (that is, without folding) over a large ...
Anatomy is often described in planes, referring to two-dimensional sections of the body. A section is a two-dimensional surface of a three-dimensional structure that has been cut. A plane is an imaginary two-dimensional surface that passes through the body. Three planes are commonly referred to in anatomy and medicine: [1] [2]: 4
They are used in anatomy, surface anatomy, surgery, and radiology. [45] Structures may be described as being at the level of a specific spinal vertebra, depending on the section of the vertebral column the structure is at. [45] The position is often abbreviated.
Orogeny (/ ɒ ˈ r ɒ dʒ ə n i /) is a mountain-building process that takes place at a convergent plate margin when plate motion compresses the margin. An orogenic belt or orogen develops as the compressed plate crumples and is uplifted to form one or more mountain ranges.
A neuron receives signals from neighboring cells through branched, cellular extensions called dendrites.The neuron then propagates an electrical signal down a specialized axon extension from the basal pole to the synapse, where neurotransmitters are released to propagate the signal to another neuron or effector cell (e.g., muscle or gland).
In anatomy, a process (Latin: processus) is a projection or outgrowth of tissue from a larger body. [1] For instance, in a vertebra, a process may serve for muscle attachment and leverage (as in the case of the transverse and spinous processes), or to fit (forming a synovial joint), with another vertebra (as in the case of the articular processes).

In the Neoproterozoic most of the Earth's landmasses were united in the Rodinia supercontinent.The majority of its bulk consisted of the landmass of Gondwana. [Note 1] Near the end of the Neoproterozoic, during the breakup of this supercontinent, Laurentia [Note 2] and Baltica [Note 3] rifted from the western (Amazonian craton) and northern (African) margins of Gondwana respectively.
The foot (pl.: feet) is an anatomical structure found in many vertebrates.It is the terminal portion of a limb which bears weight and allows locomotion.In many animals with feet, the foot is a separate [clarification needed] organ at the terminal part of the leg made up of one or more segments or bones, generally including claws and/or nails.
