  2. Tracheid - Wikipedia

    en.wikipedia.org/wiki/Tracheid

    Angiosperms have both tracheids and vessel elements. [1] A tracheid is a long and tapered lignified cell in the xylem of vascular plants. It is a type of conductive cell called a tracheary element. Angiosperms use another type of conductive cell, called vessel elements, to transport water through the xylem.

  3. Cerebral veins - Wikipedia

    en.wikipedia.org/wiki/Cerebral_veins

    3D model of cerebral veins. In human anatomy, the cerebral veins are blood vessels in the cerebral circulation which drain blood from the cerebrum of the human brain.They are divisible into external (superficial cerebral veins) and internal (internal cerebral veins) groups according to the outer or inner parts of the hemispheres they drain into.

  4. Vessel element - Wikipedia

    en.wikipedia.org/wiki/Vessel_element

    A vessel element or vessel member (also called a xylem vessel) [1] is one of the cell types found in xylem, the water conducting tissue of plants. Vessel elements are found in most angiosperms (flowering plants) and in some gymnosperms such as cycads and Ephedra, but absent in conifers. Vessel elements are the main feature distinguishing the ...

  5. Cerebral circulation - Wikipedia

    en.wikipedia.org/wiki/Cerebral_circulation

    The maturation of blood vessels in the brain is a critical process that occurs postnatally. [6] It involves the acquisition of key barrier and contractile properties essential for brain function. During the early postnatal phase, endothelial cells (ECs) and vascular smooth muscle cells (VSMCs) undergo significant molecular and functional changes.

  6. Dural venous sinuses - Wikipedia

    en.wikipedia.org/wiki/Dural_venous_sinuses

    The dural venous sinuses (also called dural sinuses, cerebral sinuses, or cranial sinuses) are venous sinuses (channels) found between the periosteal and meningeal layers of dura mater in the brain. [1] [2] They receive blood from the cerebral veins, and cerebrospinal fluid (CSF) from the subarachnoid space via arachnoid granulations.

  7. Xylem - Wikipedia

    en.wikipedia.org/wiki/Xylem

    The most distinctive xylem cells are the long tracheary elements that transport water. Tracheids and vessel elements are distinguished by their shape; vessel elements are shorter, and are connected together into long tubes that are called vessels. [6] Xylem also contains two other type of cells: parenchyma and fibers. [7] Xylem can be found:

  8. Broca's area - Wikipedia

    en.wikipedia.org/wiki/Broca's_area

    Broca's area, or the Broca area (/ ˈ b r oʊ k ə /, [1] [2] [3] also UK: / ˈ b r ɒ k ə /, US: / ˈ b r oʊ k ɑː / [4]), is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain [5] with functions linked to speech production. Language processing has been linked to Broca's area since Pierre Paul Broca ...

  9. Human brain - Wikipedia

    en.wikipedia.org/wiki/Human_brain

    The left and right sides of the brain appear symmetrical, but they function asymmetrically. [113] For example, the counterpart of the left-hemisphere motor area controlling the right hand is the right-hemisphere area controlling the left hand. There are, however, several important exceptions, involving language and spatial cognition.
