What do nerves look like under a microscope?
Nerves under a microscope appear as long, thin structures with a central core called the axon surrounded by a protective sheath called the myelin. They have a branching structure and are often found in bundles.
What are the different types of horns found in the animal kingdom?
In the animal kingdom, there are two main types of horns: true horns and antlers. True horns are permanent, bony structures covered in a keratin sheath, found in animals like cattle and sheep. Antlers, on the other hand, are temporary, branched structures made of bone and are shed and regrown annually by animals like deer and moose.
Where are the gametophytes of gymnosperms found?
The gametophytes of gymnosperms are found within the reproductive structures of the plant, such as the male cones for the pollen-producing male gametophytes and the ovules for the egg-producing female gametophytes.
What are tiny structures within the cell that have specific jobs to do within the cell?
organellesOrganelles within the cytoplasm of cells have specific functions.Structures within the cytoplasm that perform specific functions are called organelles. They are found in all eukaryotic cells.organelles
Where do we usually find the dna molecule in a living cell?
The DNA molecule in a living cell is typically found within the cell's nucleus, packaged into structures called chromosomes. In some organisms, such as bacteria, the DNA may be found in a region called the nucleoid within the cell, which is not surrounded by a membrane.
Which artery is felt when taking the pulse rate at the neck?
The Carotid pulse is found in the neck. The Radial pulse is found in the wrist.
The lower respiratory structures are found within the throacic cavity.how are these structures protected.?
protected by rib cage
What are thin hreadlike structures found within the cytoplasm of a cell?
Thin threadlike structures found within the cytoplasm of a cell are called microfilaments. These filaments play a key role in cell movement, shape maintenance, and intracellular transport.
Where can one view images of the carotid sinus?
Images of the carotid sinus can be found at Picsearch, Family Practice Notebook, The Free Dictionary, Carotid Net, Forensic Med UK, Ganfyd, and Study Blue
Which structures are contained within the petrous portion of the temporal bone?
The structures that are found deep within the petrous part of the temporal bone are related to the inner ear. Most scientists divide the structures into two parts the mastoid part and the petromastoid part.
What is the insulating layer found on the nerves?
Myelin Sheath
What is the layer of insulation found on nerves?
Myelin Sheath
Where are nodes of ranvier found?
In the fatty myelin sheath there are gaps between the axons. The myelin sheath gaps are referred to as the nodes of Ranvier.
What structures are most likely to be found at relatively high concentrations within the cells of a heat generating organ?
mitochandria
Where do organelles live?
Organelles are found within the cytoplasm of cells. They are membrane-bound structures that carry out specific functions to support the overall function of the cell. Some organelles, like mitochondria or chloroplasts, have their unique structures and roles within the cell.
Are neurotransmitters found in the myelin shealth?
No, neurotransmitters are not found in the myelin sheath. The myelin sheath is a protective covering that surrounds nerve fibers, while neurotransmitters are chemical messengers that transmit signals between neurons.
What does not belong nodes of ranvier myelin sheath cell body axon?
Cell body does not belong because the other options are all components of a nerve cell. Cell body (soma) is the main part of the neuron where the nucleus is located, while the nodes of Ranvier, myelin sheath, and axon are all structures found in the axon of a neuron.
