What are the tuft of capillaries located between the afferent and efferent arterioles called?
The renal glomerulus is a small convoluted mass of capillaries, a network of vascular tufts, encased in the malpighian or Bowman's capsule.
What the arteriole leads into the glomerulus?
The afferent arteriole leads into the glomerulus, which is a bundle of small blood vessels located within the Bowman's capsule in the kidney. This is where blood is filtered to form urine in the process of urine formation.
Why are there more arterioles in mammals than main arteries?
Arterioles carry bloo, under lower pressure than arteries, from arteries to capillaries. They also control the flow of blood between the two. In mammals main arteries are located primarily in and around the heart, whereas arterioles connect these to the capillaries
Where is blood located before it reaches the capillaries?
Arteries or arterioles
Where are arterioles located?
Arterioles are small diameter vessels that branch off of your arteries. They inevitably connect arteries to capillaries. You can find them pretty much anywhere in your body
Where is renin synthesized?
Renin is primarily synthesized and secreted by the juxtaglomerular cells in the kidneys. These cells are located in the afferent arterioles of the renal nephrons and play a key role in regulating blood pressure and fluid balance through the renin-angiotensin-aldosterone system.
Where are cell bodies of the somatic motor neurons of the spinal nerves located?
It depends on whether it is afferent or efferent. The afferent neurons have their soma, or cell body, near the sensory receptor sites in the body tissues. The efferent spinal nerve cells have their soma near the spinal cord cord in a ganglion. The gray matter in the spinal chord is mostly made up of the cell bodies of one of the three types of neurons, afferent, or sensory neurons, interneurons, which are also called association neurons, and efferent, or motor, neurons. The interneurons have their cell bodies roughly in the middle, with the dendrites projecting out to one side (usually heavily branched) and the axon projecting out to the other but each only a short distance. In motor neurones (efferent neurone) the cell body is very much at one end, with the dendrites branched directly from and the axon projecting a long way to reach the target. These neurons also have their cell bodies in the spinal column (usually) but there just are not as many of these as there are interneurons. The sensory neurones (afferent neurones) are quite like the interneurons in structure as they have their cell bodies in the middle but the distance the dendrites and the axons projects are much greater. The allows the cell bodies from many sensory neurons to be grouped together, a fair distance from the sensing tissue, what is also referred to as as affector organ, in a structure called a ganglia (the name for a collection of cell bodies in the periphery).
What is the glomerus and in which tissue of the kidney is this part of the nephron located?
The glomerus a capillary tuft which receives its blood supply from an afferent arteriole of the renal circulation. Its blood pressure provides the power to force fluids and solutes to be filtered out of the blood into the space made by the Bowman's capsule. The remaining unfiltered blood passes into the narrower efferent arteriole. It then moves into the vasa recta, the collecting capillaries intertwined with the convoluted tubules through the interstitial space where the reabsorbed substances also enter. It then joins with the efferent venules of the other nephrons into the renal vein before rejoining with the main bloodstream.
What is the Correct order of filtrate flow through the nephron?
Nephron is the functional unit of the kidney. Located in pyramids of medulla (triangular sections of the kidney). Nephron contains renal corpuscles (Glomerular capusule aka: Bowmans Capsule) which contain renal tubules (Glomerulus-filtrates blood as is flows through kidney, afferent/efferent). Waste by way of loop of Henle (exits capsule), go to collecting ducts. Kidney-renal corpuscles-afferent arteriole-bowmans capsule-glomerulus-efferent arteriole-proximal convoluted tubule-descending loop of henle-thin segment-acscending loop of henle-distal convoluted tubule-collecting ducts-major calyces-renal pelvis-uretER-urinary bladder-urethra (female 4cm long- con't from urethra-out) (male 20cm long-urethra made up of three parts-con't from urethra-prostatic urethra-membranous urethra-penile urethra-out) I believe that is correct. What confused me is the afferent/efferent/tubules. They are three separate passage ways. Aff/Eff is for blood. Afferent is where blood enters-waste goes to capsule-waste leaves capsule by 1st entering proximal tubule of loop of henle-blood that was "not" waste goes back to the body by way of efferent. Notice the difference in female and male.
What are 3 types of neurons?
Functional types of neurons: 1. sensory (afferent) neurons - input to CNS from sensory receptors; dendrites located at receptors, axons in nerves, cell bodies in ganglia outside the CNS 2. motor (efferent) neurons - output from CNS to effectors cell bodies and dendrites located in the CNS, axons in nerves 3. interneurons - communicate and integrate information within the CNS; located entirely within the CNS
Where is the juxtaglomerulus apparatus located?
The juxtaglomerular apparatus is located in the kidney, specifically at the point where the afferent arteriole and the distal convoluted tubule come into close contact in the nephron. It plays a key role in regulating blood pressure and kidney function.
Where is the nucleus located in the neuron?
The nucleus of a neuron is typically located in the cell body, also known as the soma. It is located towards the center of the neuron, where it functions to control the activities of the cell and contains the genetic material needed for cellular functioning.
