What part of the heart's conduction system acts as the primary pacemaker?
The atrioventricular (AV) node which is located in the right atrium. From there is travels down the septum, also called the atrioventricular bundle, and then spreads to all parts of the ventricles via the Purkinje fibers.
What is the function of the chemoreceptors in the carotid arteries and aorta?
I will illistrate my answers with an example: When an individual exercises, the concentration of CO2 in the blood increases, this lowers the pH, making it more acidic. Chemoreceptors in the carotid arteries and aorta detect this decrease in pH. Nerve impulses are sent to the centre of the Medulla Oblongata that increases heart rate. Nerve impulses are then sent via the sympathetic nervous system to the sinoatrial node, this increases the heart rate. Therefore this increases the blood flow to the lungs, CO2 can therefore be removed from the blood by the alveoli in the lungs.
How does water exit a watershed?
Via the mouth of the river into the sea. Also as a watershed just describes where surface water travels in the catchment water can infiltrate into the rock and travel into a different catchment / watershed.
Which blood vessels does it pass through when it leaves the heart?
Systemic via the aorta - pulmonary via the pulmonary artery.
Would it be possible to travel into the hollow earth from Antarctica via a hot air balloon?
The Earth is not hollow; so No.Were the Earth hollow, it might be difficult to control the buoyancy of the hot air balloon sufficiently to enter a hollow Earth at the poles.
How does the human heart operate?
Human heart is myogenic in nature. It consists of sinoatrial node in the right atrium below the endodermis. this node initiates the electrical impulses in heart. As it is initiator it is also called pacemaker of heart. The atrioventricular node gathers the impulses and transmits them to the purkinje fibres via. bundle of his-tawara. As atrioventricular node collects all the impulses it is also called pacesetter of heart.
How fast do nerves impulses travel?
Nerve impulses travel through nerve fibers via a action potential and the speed at which the impulse travels depends on the type of nerve fibre. This can range from 100m/s in the case of touch to 20-30 m/s when you're thinking.
Lymph leaves a lymph node via?
Lymph exits the node at its hilum, the indented region on the concave side, via efferent lymphatic vessels.
How do your hormones travel?
The endocrine glands secrete hormones directly into the bloodstream. The hormones then travel to target tissues via the circulatory system.
What part in the nervous system moves?
Its the impulses sended from neuron to neuron via synapses... it can travel within a fraction of second which helps us to escape from dangers rapidly...
Primary motor area sends impulses via to control skeletal muscles?
The primary motor cortex send nervous impulses via the pyramidal cells, down the pyramidal tracts in the spinal cord.
When activated the breathing control centers increase the rate of nerve impulses to the via the?
Diaphragm
Suprachiastic nuclei carry nerve impulses from the retina of the eye to the what?
When light enters the retina of the eyes, this signal is sent through the optic nerve to a region of the hypothalamus called the suprachiasmatic nucleus. This pathway is called the retinohypothalamic tract. From the suprachiasmatic nucleus, nerve impulses via the sympathetic nervous system travel to the pineal gland and inhibit the production of melatonin. At night, these impulses stop (because no light stimulates the hypothalamus) and melatonin production ensues and is released into the body.
What part sends messages from your brain and spinal cord to muscle cells?
Electrical impulses travel from the brain along the spinal cord and nerve fibers to the muscles.Brain send the message via nerve impulses involving neurons which use the neuro-transmitter Acetylcholine.
How do somatic sensory nerve impulses get to the brainstem from the head itself?
Somatic sensory nerve impulses get to the brainstem from the head itself via the cranial nerves. Cranial nerves are also known as cerebral nerves.
What part does the brainstem control?
The heart is a muscle with it's own ability to create electrical impulse via the sinoatrial node (SA node) that lies in the right atrium. The impulses generated by the SA node are very regular and constant. However, the SA node can be sped up or slowed down by autonomic nerve impulses that come from the brainstem. The brainstem is told how to change the heart rate by information from the hypothalamus. Thus, although the heart controls its own heartbeat, it can be modified as necessary under the control of the brainstem and hypothalamus.
What are some benefits of high speed travel via cartrainor airplane?
gh speed travel via car, train or airplane
