The artery that supplies the chin and jaw region of the head with blood is the
facial artery which is a branch of the external carotid artery. All blood from the head arises from the common carotid artery wherein it is divided to internal carotid artery (major blood supply of the brain along with the basilar artery on the posterior side) and external carotid artery (major blood supply of the head other than the brain).
The external carotid artery has 8 major branches (from inferior to superior): (1) superior thyroid artery, (2) ascending pharyngeal artery, (3) lingual artery, (4) facial artery, (5) occipital artery, (6) posterior auricular artery, (7) maxillary artery, and (6) superficial temporal artery.
Attached is a simplified photo of the branches of the external carotid artery.

<span>A human body is composed of muscles. Without it, the human body cannot function and will die. </span>
There are three types of muscle tissues: Skeletal muscle, Cardiac muscle, and Smooth muscle.
The skeletal muscle aids in the movement of the human skeleton. The 600 skeletal muscles make up 40 % of our body weight and are reliant on the signals released by our nervous system to start moving.
<span>Cardiac muscles are those muscles which encloses our hearts. They are involuntary muscles which pumps blood throughout our bodies by creating steady and rythmic pulsing. They also make our heart contract by producing electrical impulses. </span>
<span>Smooth muscles are found in the walls of blood vessels, respiratory passageways, and hollow organs. Its contracting movement is wavelike and it helps in the transfer of food through our stomachs or urine through our bladder. </span>
<span>These muscles responds to nerve impulses and other stimuli.</span>
If the stimulus reaches the threshold an action potential will be generated. If the stimulus doesn't reach it no action potential will be generated. If the stimulus will be stronger the action potential will have the same amplitude. The refractory period makes it harder to generate an action potential so they decrease the frequency of action potential production.
Answer:
1/4
Explanation:
1-Mother:
The probability to pass the disorder to her progeny is: 1 x 1/2 = 1/2
Father:
2-The probability to pass the disorder to his progeny is: 1 x 1/2 = 1/2
Therefore, the probability to have the disorder is equal to the product of both independent events, i.e., 1/2 x 1/2 = 1/4 or 25%
