Answer from: laza87

Answer and Explanation:

A couple of hours after the death of an individual or creature, the joints of the body solidify and become secured. This solidifying is called rigor mortis.

Contingent upon body temperature and different conditions, rigor mortis endures roughly 72 hours.

The partial contraction of the skeletal muscles leads to the occurrence of this phenomena.

Answer from: spotty1023

temporary rigidity of muscles after death; partial contraction of skeletal muscles

Explanation: Rigor mortis is defined as the temporary stiffness of a body's muscles and joints following death. It only lasts for a couple of hours (approximately 72 hours) depending on body temperature and other factors. Rigor mortis is caused by the skeletal muscles partially contracting resulting in stiffness. This causes the muscles to be unable to relax, leading to the body's joints becoming fixed in place.

Answer from: Quest

the apgar score is 6

here are the 5 factors that are observed when calculating the apgar index:

skin color

blue everywhere - 0 points

white on the ends and pink on the body - 1 point

all pink - 2 points

heartbeat

absent - 0 points

slow - 1 point

fast - 2 points

reflexes

no answer: 0 points

responds to stimulations: 1 point

cries and coughs: 2 points

muscle tone

soft: 0 point

some bending or stretching: 1 point

active movements: 2 points

breathing

absent: 0 points

weak or irregular: 1 point

good and your baby is crying: 2 points

it is estimated that children whose score is between 8 and 10 are in perfect health and need only routine care. a score between 5 and 7 is representative of a fair condition. often this means that the child has suffered during delivery and probably needs with breathing. as a first step, your doctor will carefully rub the skin of your baby or give him oxygen with a mask.

Choose the incorrect statement (a) the motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. (b) propagation of an action potential through the t-tubules into the sarcoplasmic reticulum triggers the release of ca++ into the cytoplasm of a skeletal muscle fiber. (c) the generation of suprathreshold endplate potentials in multiple muscle fibers could be due to the increased frequency of action potential generation at the axon hillock of a single motor neuron. (d) a greater amount of ach would be found in the presynaptic vesicles of a motor unit that fired several action potentials after exposure to botulinum toxin, than in a motor unit that fired several action potentials after exposure to the venom of the krait snake (which contains α-bungarotoxin).
