What is the lens of the eye and what is its function? - Socratic
Aug 11, 2014. The lens is found in the posterior chamber of the eye. The lens is part of the middle coat of the eye. It is held in place by suspensory ligaments extend that from the ciliary processes on the lens to the ciliary muscles which function to hold the lens in place and cause it to change shape. The lens, by changing shape, functions ...
What are the three layers of the human eye? - Socratic
2016年2月13日 · The vascular coat or Uveal tract is the middle coat of the eye ball. It consists of three parts : Iris, Ciliary body & Choroid. Uveal tract gives nutrition to the intraocular structures. The nervous coat or Retina is the inner coat of the eye ball. It receives stimuli in the form of light and performs visual function.
What are the 6 extrinsic muscles of the eye and their functions?
2016年2月26日 · 1 Answer. Superior rectus, Inferior rectus, Medial rectus, Lateral rectus, Superior oblique, Inferior oblique. The following two diagram shows the extrinsic muscles of the eye and their function : Superior rectus, Inferior rectus, Medial rectus, Lateral rectus, Superior oblique, Inferior oblique.
Reflex Response - Biology - Socratic
An effector is a muscle or gland that receives the impulse form the motor neuron. In somatic reflexes, the effector is skeletal muscle. In autonomic (visceral) reflexes, the effector is smooth or cardiac muscle, or a gland. An example of this that often used to check the status of a head injured person is: The constriction of pupils in response ...
Stimulus-Response Model - Biology - Socratic
The sound of the gun is sensed by the ears and a message is sent by the central nervous system to the legs and arms. Muscles contract which allow the runner to explode out of the blocks. The sound of the gun is the stimulus, the athlete starting to run is the response. Video from: Noel Pauller. mrpauller.weebly.com · 6 · Sep 10 2015.
Amplitude, Period and Frequency - Trigonometry - Socratic
Explanation: Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.
Fundamental Identities - Trigonometry - Socratic
Note that the graph of an even function is symmetric about the #y#-axis, and the graph of an odd function is symmetric about the origin. Examples #f(x)=x^4+3x^2+5# is an even function since
How can I calculate the number of photons emitted per second?
2015年4月27日 · E h = n ⋅ ν → the term n ⋅ ν should have units of photons/second. According to the equation E = n * h * nu (energy = number of photons times Planck's constant times the frequency), if you divide the energy by Planck's constant, you should get photons per second. E/h = n * nu -> the term n * nu should have units of photons/second.
How do you find theta? - Socratic
2016年9月18日 · To find theta, you use the arccos function, which has the same relationship to cosine as arcsin has to sine. And again, you may see arccos written as cos^ (-1)theta. So if costheta=a/c, then arccos (costheta)=arccos (a/c) or theta=arccos (a/c). To answer your question directly, any trig function can be used to find theta, as long as you have at ...
Solutions Using the Discriminant - Algebra - Socratic
Explanation: The discriminant indicated normally by #Delta#, is a part of the quadratic formula used to solve second degree equations. Given a second degree equation in the general form: #ax^2+bx+c=0# the discriminant is: #Delta=b^2-4ac#. The discriminant can be used to characterize the solutions of the equation as: 1) #Delta>0# two separate ...
