Smooth Endoplasmic Reticulum01:21

Smooth Endoplasmic Reticulum

8.1K
Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

Functions of Smooth Muscles01:23

Functions of Smooth Muscles

3.4K
Smooth muscles are an important type of muscle tissue that plays a vital role in the involuntary movements of internal organs. For example, they help regulate the movement of food through the gut and the flow of blood through the circulatory system.
Function of visceral smooth muscles
Visceral smooth muscle is found in the walls of all hollow organs, except the heart, and is a key player in the involuntary movements that drive the functioning of these internal organs. This tissue is arranged in...

Anatomical Movements00:51

Anatomical Movements

16.2K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

Smooth Muscle Contraction01:25

Smooth Muscle Contraction

7.9K
Smooth muscle contraction is a complex process vital for various bodily functions, from maintaining blood vessel tension to facilitating the movement of food through the digestive tract. Unlike striated muscles, smooth muscle contraction begins more slowly and lasts longer.
The onset of contraction is triggered by an increase in calcium ions within the sarcoplasm, similar to the process in striated muscle. However, smooth muscles have a relatively smaller reservoir of the sarcoplasmic...

Speed of Sound in Gases01:08

Speed of Sound in Gases

4.1K
The speed of sound in a gaseous medium depends on various factors. Since gases constitute molecules that are free to move, they are highly compressible. Hence, sound waves travel slowly through gases. Thermodynamics helps us understand the relationship between pressure, volume, and temperature of gases, thus, the speed of sound in an ideal gas can be determined using the laws of thermodynamics. At the same time, Newton's laws of motion and the continuity equation of fluid dynamics also come...

Speed of a Transverse Wave01:13

Speed of a Transverse Wave

4.0K
The speed of a wave depends on the characteristics of the medium. For example, in the case of a guitar, the strings vibrate to produce the sound. The speed of the waves on the strings and the wavelength determine the frequency of the sound produced. The strings on a guitar have different thicknesses but may be made of similar material. They have different linear densities, and the linear density is defined as the mass per length.
One of the key properties of any wave is the wave speed. Light...

Summary

Visual speed preference persists even during eye movements like smooth pursuit. This suggests our motion perception system prioritizes speed, regardless of how the eye moves or visual cues are presented.

Area of Science:

  • Visual perception
  • Neuroscience
  • Psychophysics

Background:

  • Current research on visual speed perception is limited to static images and small motion patches.
  • Active observers utilize retinal flow and extraretinal signals for motion judgment during eye movements.

Purpose of the Study:

  • To investigate if speed remains a primary dimension in motion perception during smooth pursuit eye movements.
  • To determine the generality of visual speed preference in active observers.

Main Methods:

  • Employed a "discrimination-contour" technique to assess motion perception during smooth pursuit.
  • Manipulated stimulus speed, distance, and duration.
  • Included conditions with retinal flow and isolated extraretinal signals.

Main Results:

  • Observers had the most difficulty discriminating stimuli with identical speeds but varying distances and durations.
  • This difficulty persisted even with added retinal flow and when relying solely on extraretinal signals.

Conclusions:

  • Preferential sensitivity for visual speed is a general feature of human motion perception.
  • This sensitivity is supported by diverse motion mechanisms employed by active observers.
