give one function of the following:
1) lenticels.
2) cerebellum.
3) hypothatalumus.
4) meninges.
5) node of raniver.
6) ureater
Answers
1)Lenticels facilitate the gas exchange of oxygen, carbon dioxide, and water vapor in plant bodies that produce secondary growth.
2)The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements
3)hypothalamus plays a crucial role in many important functions, including: releasing hormones. regulating body temperature. maintaining daily physiological cycles.
4)The primary function of the meninges and of the cerebrospinal fluid is to protect the central nervous system. The pia mater is the meningeal envelope that firmly adheres to the surface of the brain and spinal cord
5) Nodes of Ranvier are gaps in the myelin sheath coating on the neural axon. ... The nodes of Ranvier allow for ions to diffuse in and out of the neuron, propagating the electrical signal down the axon.
6)The ureters function as an urinogenital channel that opens up into the cloaca. Thus the ureters are carrying to the cloaca both sperm and excretory wastes.
Hope this helps you
Answer:
1)A lenticel is a porous tissue consisting of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the bark of woody stems and roots of dicotyledonous flowering plants.[2] It functions as a pore, providing a pathway for the direct exchange of gases between the internal tissues and atmosphere through the bark, which is otherwise impermeable to gases. The name lenticel, pronounced with an [s], derives from its lenticular (lens-like) shape.[3] The shape of lenticels is one of the characteristics used for tree identification.
2)The cerebellum is a vital component in the human brain as it plays a role in motor movement regulation and balance control.
4)The primary function of the meninges and of the cerebrospinal fluid is to protect the central nervous system. The pia mater is the meningeal envelope that firmly adheres to the surface of the brain and spinal cord.
3)One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland. ... The hypothalamus controls body temperature, hunger, important aspects of parenting and attachment behaviours, thirst, fatigue, sleep, and circadian rhythms.
5) Nodes of Ranvier are gaps in the myelin sheath coating on the neural axon. ... The nodes of Ranvier allow for ions to diffuse in and out of the neuron, propagating the electrical signal down the axon. Since the nodes are spaced out, they allow for saltatory conduction, where the signal rapidly jumps from node to node.
6)The ureters function as an urinogenital channel that opens up into the cloaca. Thus the ureters are carrying to the cloaca both sperm and excretory wastes. For female frog, the ureters and oviduct in the cloaca develop independently. Therefore, The ureters in frog, therefore act as sperm carrier and ova carrier.
