Arrector pili
Tiny muscles attached to hair follicles that pull the hair upright during fright or cold?
The muscles are called arrector pili and they pull the hair upright for both of those reasons and a few others.. let me know if you want to know more :)
What is the function of arrector pili muscles and situations that might cause these mucles to contract?
Is attached to the base of the hair follicle and terminates at the epidermis. When this muscle contracts it pulls the hair upright and bunches the skin (goose bumps). This action means that the air is trapped between the hair and helps to insulate the body. The muscle contracts automatically when the body is cold.
What muscles are worked during an upright row exercise using a resistance band?
During an upright row exercise using a resistance band, the muscles primarily worked are the deltoids (shoulders), trapezius (upper back), and the biceps (front of the upper arm).
How feathers attached to the wing?
Feathers are attached to the wing via structures called follicles, which are embedded in the skin. Each feather grows from a follicle, with a shaft (rachis) that extends from the follicle and is surrounded by barbs that interlock to form the feather's surface. The arrangement and structure of these feathers are crucial for flight, providing lift and aerodynamic efficiency. Additionally, the muscles and skin around the follicles allow for some movement and positioning of the feathers during flight.
During a woman's lifetime how many primary follicles fully develop into mature follicles?
400 to 500.
What can a test tube be held upright with?

How can I safely transition my newborn from sitting to an upright position?
To safely transition your newborn from sitting to an upright position, start by supporting their head and neck until they have developed enough strength to hold it up on their own. Gradually increase the time they spend in an upright position to allow their muscles to strengthen. Always supervise your baby during this transition to prevent any accidents or falls.
Can individual muscles pull in only one direction?
all of them, muscles can only contract and relax
The human rectus abdominis is definitely divided by four transverse tendons. These tendons are absent or difficult to identify in the cat. How do these tendons affect the human upright position?
The tendons in the human rectus abdominis act as focal points for muscle contraction, providing stability and support to the torso during upright posture. They help maintain proper spinal alignment and distribute forces evenly throughout the core muscles to prevent excessive strain on the spine. Their presence contributes to the overall strength and functionality of the abdominal muscles in supporting the body's upright position.
What is the Function of Graafian follicles?
Graafian follicles are mature ovarian follicles that contain a developing oocyte. Their function is to produce estrogen and prepare the egg for ovulation. When the Graafian follicle ruptures during ovulation, it releases the egg into the fallopian tube for possible fertilization.
