What are the bony attachments for all the muscles of facial expression?
Expert Solution & Answer
Summary Introduction
To determine:
The bony attachments for the muscles of facial expressions.
Introduction:
The muscles control all the body movements. Axial muscles are the muscles that control facial expressions. These muscles also support the head. The axial muscles control the movement of the head and spinal column. They are involved in non-verbal communication.
Explanation of Solution
The muscles of facial expression attach to the superficial fascia of the skin. These muscles contract after joining with superficial fascia. The contraction and relaxation of these muscles control the facial expressions. All the muscles of facial expression attach with superficial fascia except the facial nerve. The facial nerve attaches to the seventh cranial nerve.
Thus, superficial fascia of the skin is the bony attachment for the muscles of facial expressions.

In a natural population of outbreeding plants, the variance of the total number
of seeds per plant is 16. From the natural population, 20 plants are taken into
the laboratory and developed into separate true-breeding lines by self-
fertilization-with selection for high, low, or medium number of seeds-for 10
generations. The average variance in the tenth generation in each of the 20 sets
is about equal and averages 5.8 across all the sets. Estimate the broad-sense
heritability for seed number in this population. (4 pts)

You pick Jackalopes that have horn lengths around 1.75 feet to breed as this appears to be the optimal length for battling other Jackalopes for food. After a round of breeding, you measure the offsprings' mean horn length is 1.67. What is the heritability of horns length (h2)? Is Jackalope horn length a heritable trait?

- Kinetics: One-Compartment First-Order Absorption 1. In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple routes of administration provides greater insight than a single route of administration alone. The following data was collected in 250-g rats following bolus IV, oral (PO), and intraperitoneal (ip) administration. Using this data and set of graphs, determine:(calculate for each variable) (a) k, C0, V, and AUC* for the bolus iv data (b) k, ka, B1, and AUC* for the po data c) k, ka, B1, and AUC* for the ip data (d) relative bioavailability for po vs ip, Fpo/Fip (e)absolute ip bioavailability, Fip (f) absolute po bioavailability, Fpoarrow_forward3. A promising new drug is being evaluated in human trials. Based on preliminary human tests, this drug is most effective when plasma levels exceed 30 mg/L. Measurements from preliminary tests indicate the following human pharmacokinetic parameter values: t1/2,elim = 4.6hr, t1/2,abs = 0.34hr, VD = 0.29 L/kg, Foral = 72%. Based on these parameters, estimate the following if a 49 kg woman were to receive a 1000mg oral dose of this drug: (a) Estimate the plasma concentration of the drug at 1hr, 6 hr, and 20hr after taking the drug ( Concentration estimate) (b) Estimate the time for maximum plasma concentration (tmax). (c) Estimate the maximum plasma concentration (Cmax). (d) Estimate the time at which the plasma level first rises above 30 mg/L. (Note this is a trial and error problem where you must guess a time, plug it into the concentration equation, and determine if it is close to 30 mg/L. Hint: based on part (a) it should be apparent that the answer is less than 1hr.)
