What else can I help you with?
Which of these parts receive nerve impulses from the central nerous system causing muscle fibers to contract?
The motor neurons carry impulses from the central nervous system to the muscles. These impulses may be generated autonomically (instinctively) or through voluntary control by the brain.
What is the job of a leg muscle cell?
Receive stimulatory impulses to contract and inhibitory impulses to stop contraction from the neuromuscular junction. This contraction is carried out by Ca2+, ATP and the actin and myosin proteins in the cells, forming a sarcomere. By contracting and relaxing as a syncytium, the leg muscle can control the joint(s) it crosses and produce movement.
What conducts impulses from the brain to glands?
Nerves transmit impulses from the brain to glands. This communication pathway enables the brain to control the release of hormones that regulate various bodily functions.
In an experiment a group that receives no treatment is called what?
The group that receives no treatment in an experiment is called the control group. This group is used as a point of comparison to evaluate the effects of the treatment applied to the experimental group.
What organ sends signals and impulses?
The brain is the organ that sends signals and impulses throughout the body. It processes information received from sensory organs and coordinates responses by transmitting electrical signals via neurons. This complex network allows the brain to control various functions, including movement, cognition, and emotion. Additionally, the spinal cord acts as a critical pathway for these signals between the brain and the rest of the body.
Which structure of a feedback system receives output from the control center?
The structure that receives output from the control center in a feedback system is typically the effector. The effector is responsible for carrying out the response dictated by the control center to maintain homeostasis or achieve the desired outcome.
Which of these parts receive nerve impulses from the central nerous system causing muscle fibers to contract?
The motor neurons carry impulses from the central nervous system to the muscles. These impulses may be generated autonomically (instinctively) or through voluntary control by the brain.
What is the word to describe the control of one's impulses?
willpower
What do electrical impulses of the brain cause?
Electrical impulses of the brain are the nervous impulses that the nervous system uses to control body functions. These impulses may be relayed within the brain, or may be carried to the peripheral nervous system.
What is the difference between ascending and descending impulses?
Ascending impulses refer to nerve signals traveling towards the brain, carrying sensory information from the body. Descending impulses, on the other hand, refer to nerve signals traveling from the brain down the spinal cord to control motor functions and movement in the body.
What is the job of a muscle cell?
Receive stimulatory impulses to contract and inhibitory impulses to stop contraction from the neuromuscular junction. This contraction is carried out by Ca2+, ATP and the actin and myosin proteins in the cells, forming a sarcomere. By contracting and relaxing as a syncytium, the leg muscle can control the joint(s) it crosses and produce movement.
What transmits impulses that activate and control body functions?
the nervous tissue
Impulses from motor neurons control the contraction of skeletal muscles?
false

Do muscle cells work together to allow movement?
Muscle cells contract and relax in response to nerve impulses, causing movement. The human body has three types of muscle cells. Skeletal muscle cells control movement of bones, such as our arms and legs.
What is group that receives no treatment in an experiment?
the control.
How would a nerve cell carrying impulses from your brain to your eyelids be different to one carrying impulses to your heart?
A nerve cell carrying impulses from the brain to the eyelids is typically a motor neuron, specifically a somatic motor neuron, which controls voluntary movements. In contrast, a nerve cell transmitting impulses to the heart is part of the autonomic nervous system, specifically a sympathetic or parasympathetic neuron, which regulates involuntary functions. The structure, neurotransmitter types, and pathways of these neurons differ, reflecting their distinct roles in motor control and autonomic regulation.
